Hello all,
i have around 10 Files with the name above in my XDA some of them with a size of 260k and some with 1,65Mb. What are they good for or where are they from.
I can´t delete them and I don´t see them in the memory usage.

Huge MsgQueue.. files in Windows directory
I have the T-Mobile Pocket PC with just the built-in 32MB of RAM (256MB SD card on order...)
In my case there are a bunch of MsgQueue-blah-blah files in the Windows directory, 7 of which are 1.65MB each. Plus a 3.83MB file called "rsupgrade.cp64". That's about 15MB.
Unfortunately I don't have an answer, only an additional question... hopefully someone can answer us both.
Are these eating into my RAM or am I seeing files from ROM? I suspect RAM since they change periodically. Are they critical or can I delete them? If the latter, is there a way to limit their size or prevent them from reappearing?
T-Mobile Customer Care level-3 support was relatively clueless as usual, but they did suggest that I could do the following to determine how critical those files were:
1. Perform a backup
2. Do a hard reset
3. Check and see if the offending files went away
4. Restore from backup
If the files went away, then supposedly you should be able to delete them yourself if/when they reappear later. But realize that's just the CC guy's theory, and he didn't sound too sure of himself. I'm sure the regulars in this forum could provide a much more intelligent analysis.
Any help?
Thanks.
(some?) T-Mobile MDA's have an rsupgrade as part of ROM, as they perform a phone upgrade as part of a ROM upgrade. Which has really surprised a few people with the 'wrong' phone (900/1800 as opposed to 900/1900) as they then had to struggle to get phone functionality back.
You can try deleting the file, it no longer serves a purpose after the phone is upgraded. But if it won't delete, I would suspect it's in ROM, and in that case it's not bothering you.
Odd
Emboldended by your advice (Peter Poelman) I prepared to delete the rsupgrade file by first backing up through ActiveSync. However, after doing so, the offending file was gone. Stranger yet, I don't think I reclaimed any memory as a result... (hadn't recorded "before" amount yet - was going to do that after backup. But I think I would notice a 4M difference)
Well, either way, that's one down... Could you (or someone) comment on the MsgQueue* files? They all seem to be SMS related. How MicroSoft could justify allocating nearly *half* of the unit's available ram for some SMS caches is beyond me... Well, for M$ I guess it's not surprising, given the alleged unholy alliance between M$ and the RAM industry.
these files are actually in ROM, not RAM but it's impossible for the end user to know that from the properties of the file. Likewise, according to microsoft, those files are not reporting what is actually being used, it may say 1.7megs but it's not really. Per MS, do not try to delete these files as doing so would render the device broken. I think they have to do with the messaging portion of the PPCPE.
Thanks
Useful info, thanks.
ok, i was reading sum1 else's thread, about a memory leak....they were talkin about notifications, but i can easily just delete those.
my problem is a file called : "MsgQueueDataFilMicrosoft Raw SMS Protocol (receive only)" I have 7 of them and they are each 2784k!
and also sum called MsgQueueMapFileMicrosoft Text/ WDP/ wcmp/ etc etc SMS Protocol
and the are 7 in total also, and are 262k each
what r they, wut r they 4, and why are they so big, and how can i get rid of them, or should i evenwant to?...all i know is not too long ago, i had more available memory :evil:
NO ONE....NOTE EVEN A COMMENT :shock:
Hi ...
even if youdon't have clear description for the content of those files, but you should notice that they will be there even after a hard reset. This means they are CE system files and were not just created by corrupted s/w.
Up my my information, they are to handle the messaging services for different streams (SMS, windows messaging, e-mails, ... etc).
if you still bothered with space issue, why don't u get bigger RAM or SD card ????? :wink:
CAN U DO ME A FAVOR, AN TELL ME THE SIZE OF UR FILES AN HOW MANY OF THEM U ACTUALLY HAVE??
I KNOW THEM FILES ARE NEEDED....BUT THE FACT THAT THEY GOT BIGGER IN SIZE IS BUGGING ME, OR MAYBE THEY WERE ALWAYS THIS SIZE, AN SUM OTHER PROG IM NOT AWARE OF IS TAKING UP MY SPACE
I WAS KINDA OF INTERESTED IN A RAM UPGRADE, BUT THEN I FIGURED, IF IMA DO THAT, ILL JUST GET THE I-MATE, OR THE i700...ANY WAY I DO HAVE A SD CARD, BUT I WANTED TO FREE UP AS MUCH POSSIBLE MEM FOR RUNNING PROGRAMS
THANX
they are the same on every device and have constant size
7 pairs: 2.71 MB and 262 KB
Most likely they are sort of swaping pages.
The don't actually consume any space. Don't worry about it.

Sorry to make a whole new thread about this, but just curious if anyone else has been having this 'issue'
ive flashed quite a few of the roms on the forums, and for some strange reason, i cant seem to find a rom which just WORKS
the main thing i use my handset for is email and SMS messaging, in any given month easily 4000+ SMS' will be sent and the same number received.
this for some reason appears to 'break' a lot of the rom's
the phone slow's riiiight down and when exiting one conversation to go to the next, it hangs every single time, when i go to select the messaging application, it just hangs, or doesnt even go in at all.
i've used the Energy roms, the Chrome roms, Da_G's clean rom, NATF's roms
i've been through pretty much all of the rom's on here and they ALL break once the SMS count gets in the 3000+ region, and i appreciate its simple to just 'delete' the messages, but this isnt particularly practical, at the moment i'm having to hard reset every month or so and this really takes the piss
can anyone point me in the direction of a nice lean rom that can handle an obscene amount of SMS' and emails?
with thanks
I guess no one send and receive 4000+ SMS' per month except you
that's why nobody tried to check with this issue
but the phone should be able to handle it! i mean, one of my older nokia's can handle the 4000+ with ease
The microsoft SMS program just cannot handle that many of messages. Either back them up (remove from inbox) periodically, or delete them periodically.
you may want to disable sms conversation (threading).
just out of curiosity, why do you need 4000+ sms a month ?
one question... where are your messages stored? in phone memory or on the storage card?

for the email, the attachments are stored on storage card
otherwise, i never knew we could change where SMS's are stored?!
the 4000+ sms's are just what i use tbh, thats on a good month tho, usually hovers around that mark however
i remember back in the wizard/hermes time clean rom's were all the rage, now, since we've got the devices with huge amounts of ram/rom all we're seeing is bloated rom's!

the thing is, i use the threading facility a LOT, back before wm6/6.1 i actually had an application i would install on my ppc to have the SMS' threaded
but to be honest, why should the tp not be able to handle that many SMS's without slowing down?!

I dont think this would be the ROMs fault. You see the more messages you store in your fone the less memory and stability it has. Instead of having old messages in your fone why not delete them? Talk about practicality, whats practical about having old messages in ur fone just to take up excess memory? So someone texts u one question, u answer it and have no intentions of messaging them back, yet its more practical to keep these messages in ur fone and then complain that u have to hard reset instead of deleting a few messages due to having all these redundant mesages that u really dont need? Seems to me an intelligent person would rather delete a few messages rather than hard resetting their device and lose everything. Maybe u can make a fresh ROM with no extras and nothing more than a fone and an email device. I mean, why have a PDA if all ur gonna do is text and email? Seems to me u can save a few hundred bux and just get a cheap lil fone that has no customization whatsoever to leave all the room for messaging? Sorry if I sound like I have an attitude, honestly I dont, I just think that the chefs u mentioned have awesome ROMs that keep getting better and better yet u diss them cuz ud rather hard resest and lose everything rather than simply deleting a few hundred messages that u dont need anyway.
It's like if you don't clean your house regularly and just throw your rubbish everywhere, then you complain that you're living in a pig sty and your house fills up with rubbish so fast you can't move around the house as quickly as you used to. Then after a month, you need to fully renovate the whole interior of the house again so that you have space to walk...
My suggestions :
1) start learning some housekeeping(make that little effort to delete the sms yourself)
2) get a bigger house (new phone with more ram and faster CPU)
3) get a cleaner to come in to clean your rubbish once in awhile (there might be some sms program out there that can auto delete your sms on a regular basis)
4) or reorganise the layout of your house so that it's more efficient (forget about sms threading and use the conventional format, I'm sure it'll speed things up a bit since it doesn't have to load the entire conversation everytime)

Is your older nokia using sms threading and displaying the whole history of the conversation everytime you enter the inbox?
I highly doubt it.. so you've got your answer there already.
I used to be a project manager, I would send about 500 emails a day at work easily. After a month of working it would take FOREVER to open outlook. Thats because it has to load the entire contents of 10k + emails. Its the same with your phone. Back up and delete or don't complain. Flash a stock ROM and open your windows folder, and then flash a custom ROM and do the same. you will see the speed increase there. Also, if you leave SMS open and just hit end key it wont have to reload everything every time you open a message.
I have the same problem that your talking about since i average about 7-12K a month of sms.. Like everyone said the only way to deal with it is just to clear your inbox or put it to unthreaded.. Our phones just werent meant to hold that much sms i suppose..

I believe most of the problem here is that you don't precisely understand what's going on behind-the-scenes. Your CPU/processor is only capable of running a single instruction at once- and thus only process a finite amount of data per unit time.
When designing an algorithm (in this case, the algorithm that reads SMS/E-mail database entries and displays them onscreen), tasks which apply to more than one or two items are usually completed by either iteration or recursion. For a task such as enumerating SMS messages onscreen, the process would be iterative; for example, if you were to break it down into simple steps, those steps might be:
1. Read the current SMS message from the database.
2. Display it on screen.
3. If there's another text message after this, repeat this process for it.
Step 1 itself actually is composed of several detailed steps, which take the time to perform a second algorithm, which tries to locate the current SMS message in the database, usually based on a unique identifier and a hashing algorithm. This takes time, but is faster than the alternative- which is to check each SMS and ask "is this the one I want?". Instead of having to check each message, the device usually only has to check a few until it finds the right location.
You can think of this as the device automatically categorizing messages into virtual 'boxes'- you have to spend a hell of a lot less time digging through a box to find 1 document out of 10 then by searching through a much larger heap of 4000 documents.
Step 3 is also composed of several steps, as the device has to figure out which SMS message is really next. As the user is capable of configuring the way in which the messages are sorted (by date, sender, etc.), the message that's next in the database is probably not the next message that's stored in the database. Time has to be spend finding the message, usually by yet another algorithm.
The problem is, each of these steps, and each of their sub-steps, and each of the sub-steps required to run those (all the way down to the machine code level) take time, and each have to be executed for every message the application would like to display.
Thread-view further complicates the matter by creating additional relations between the messages, and requiring the OS to look for even more posts during each step.
And this process isn't all that's going on at once- the operating system is trying to do something called TDM, or Time-Division Multiplexing (Multitasking), which allow you to run more than one program at once on a single CPU (which in turn can only do one thing at once). This basically lets the individual processes take individual turns so quickly that they seem simultaneous.
Because of all this, computer scientists rate their algorithms by degradation. We actually have a measure called Big-O (asymptotic) notation that tells you how well an algorithm handles load.
A good algorithm generally has performance of O(N) or better. This means that for every N elements (in your case, e-mail), it takes approximately N iterations to complete. Note the assumption that each "base iteration" executes in a (roughly) fixed time.
Assuming the WM message app uses a sensible algorithm (and it would be difficult for it not to), we can assume its efficiency is approximately O(N)- as it is simply O(N) for non-threaded, and it is O((N/S) * S) for threaded, which simplifies to O(N). This means that for every 4000 messages, it will need to iterate 4000 times.
Considering the application can't store 4000-messages worth of data, it spends a lot of time during each iteration moving messages in and out of memory.
Given all of this, the Windows Mobile message parsing algorithm is the cause of your 'slowness' and 'hangups'. These periods of non-responsiveness are simply WM trying to run through the algorithm for all of the huge quantities of messages.
Hence, the problem is that Windows Mobile simply wasn't designed to bear the load you were forcing it to bear. This means the problem isn't related to the implementation in any given ROM.
can anyone point me in the direction of a nice lean rom that can handle an obscene amount of SMS' and emails?

A ROM isn't going to be your solution- every ROM uses the same core Windows Mobile messaging applications.
It is possible that a combination of a data structure and message parsing algorithm (with the addition of hash and cache optimized for the way you specifically use messaging) could handle all of these messages without any considerable degradation; but it would run far less efficiently on small amount of messages than the current WM scheme. (And think: how many users have as many messages as you?)
Since no one really needs as many messages as you seem to, consider your options:
1) Implement a database optimized for large amount of messages. Implement a program that hooks all messages and places them in this database instead of the WM one. Write your own message reading/writing application and use in place of the WM one. Note that no one will do this for you. It's not a public interest: if you want it, you'll have to write it. We can help you- but we're not here to do the work for you.
2) Try a third party SMS reader/writer like Vito SMS-Chat. I don't think these will fare much better (in fact, they may fare worse), but if they implement any database of their own and any type of localized caching (especially of recent messages), they may work a bit better.
3) Remove your older SMS messages. This is probably the best option. If you don't need those messages anymore, a Microsoft applet called InboxExtender adds buttons to delete all messages (and to mark them all as read.)
4) Don't use threaded mode. This will decrease the time each parsing iteration takes.
---
This isn't a bug; nor is it a glitch, nor is it WM being crappy. It's much the same as if you tell photoshop to open an 8GB file on your desktop. Your computer may slow to a halt and take forever doing it- but the cause isn't that your computer is crappy, but rather that you're trying to open such a huge file.
Wow! Talk about a detailed explanation. Great explanation ktemkin, u obviously know what ur talkin about. Im actually a part time computer programmer. The biggest problem I see/hear about is people sayng their systems are getting way too slow. No surprise that the biggest reason for this is the used space in their computers hard drive for out-of-date programs, used cache space, ...basically all of the things theyve used before and just never cleaned out. I install 1 program, free their computer up of its junked up memory and update their programs. On this I get credit to simply sit on my butt and delete a few things, lol. Id suppose regardless of the device/computer its all the same. IE, the more room u have to work with, the faster the device's responsiveness is.
Best advice for these PDAs and smartphones for emails is dont leave all of your emails in your inbox folder. Make different folders, then as u go through your emails simply move the selected ones to the selected folders. Then DO NOT sync all of your folders to your device. Only sync the inbox to your device. Then if u ever need a message, u will know which folder its in, then sync that 1 folder, download the message(s), then after ur done, remove that folder from your sync list. When u organize your emails this way u will have a much enjoyable and longer life experience with your device. Hope this helps.

The fact of the matter is, that a lot of the messages on my handset DO need to remain on there for at least the remainder of a fortnight following receipt of said message.
the only 'qualm' i was having was that my older wizard and hermes devices seem to have managed that number of SMS' and more perfectly fine, but my Raphael begins to struggle.

my emails are already pretty much organised, and i've only got it syncing the last 7 days for me, emails to be honest are fine its moreso the SMS side of things.
I was not complaining nor targetting any particular chef, i was merely voicing my concern that a device as powerful as the raphael seems to baulk at the prospect of a few thousand messages when the older wizard and hermes seem to manage perfectly fine.
i'm not exactly expecting an instantaneous loading of my inbox, i'm not entirely thick, i appreciate that having such a large number of SMS' will inevitably slow the handset down, however, i do not see why the handset should HANG when i try to open the messaging application, or why, when i try to go and open the messaging application it just doesnt register that i've asked it to open the application, just stops and i have to 'tap' it a few times before it opens.

4000+ sms' send AND receive???
so that means:
8000 per month / 30 days in a month = 266,667 per day
266,667 per day / 960 minutes (16 hours * 60) awake a day = 0,278
so say you are 16 hours awake on a day than you send/receive a sms every 15 seconds?? don't you have a real life?

not all of the messages that are sent and received are single SMS' long!
majority, if not all will be 3/4+ messages long and the replies can be twice as long

1 thing's for sure, the wizard and hermes are definitely non-threaded sms. But it's hard to compare apple to apple. Did you have 4000 in your Inbox and Sent folders on your Wizard and Hermes too?
I don't think the phone has hung, it's probably doing the processing for you. Have a little patience and let it sit there for awhile and do it's thing and see if it's really hanged.

Maybe you should try Da_G's test ROM.. the feedback is that it's very fast. If that doesn't work for you, it's time to get a new phone.. maybe consider one of the 1GHZ models...
i have 8000 plus messages on my tp n it doesn't slow down
thing is, i don't use threaded sms. can't get used to it cos i've been using wm since wm5 n it doesn't have it. i guess i got used to the older stuff
Hello XDA-Developers!
I had an idea this morning.
Current Transfer Tech:
Bluetooth - Requires the user of both devices to enable their bluetooth devices, then they have to go about pairing the devices to allow file tansfer (this is not always the case though). then the, shall we call him "sender" has to select a file and attempt to bluetooth the file to the, shall we say "reciever", who in turn has to accept the data and then the transfer starts.
Wifi - not used very often but files can be transferred through an app or through an ftp server etc from one device to another. this however requires a little, if not more, skill to complete and can be fustrating looking for ip addresses etc.
NFC - this is an emerging technology that is being implemented in more and more devices such as the Galaxy Nexus. This is a very efficient and fast way to transfer data from one NFC enabled device to another NFC enabled device, however like most of the android community, my phone does not have this capability.
My Idea:
This is just an idea and you may say what you like about it but i thought i would write it down here, the first place that came into my mind where i thought that someone could take this idea further.
Now my friend uses a blackberry, and i know that that word is almost taboo on this forum but hear me out. He uses his blackberry for a service called BBM (Blackberry Messenger), i am sure you are all familiar, and to add a friend of his so that he can contact them using the service, he simply uses his blackberrys camera to scan a 2D Barcode on his friends device and all his BBM Pin and other data is transfered through the phones camera so that they can communicate on the service.
I though that this could be used more on android devices. This could be used to transfer small files from one device to another such as contact information, websites (already a reality), even larger files such as word documents and other reletavely small documents. Now i know that these files cannot be displayed on a single 2D barcode but maybe they can be send using not one barode but a series, the barcodes could be in an animation on the device screen, showing one barcode after another all and the "reciever" could simply hold his device's camera over the animation and it could read the series of barcodes and then compile all of the data to create a single document.
Now i realise that this could be a silly idea as the ammount of data that can be transferred through a 2D barcode is not huge, al lot of barcodes would be needed to transfer a larger file than someones contact details.
Let me know what you think, and you are free to do what you want with my idea, i wont hold it against you

This is just an idea and you may say what you like about it but i thought i would write it down here, the first place that came into my mind where i thought that someone could take this idea further.
Now my friend uses a blackberry, and i know that that word is almost taboo on this forum but hear me out. He uses his blackberry for a service called BBM (Blackberry Messenger), i am sure you are all familiar, and to add a friend of his so that he can contact them using the service, he simply uses his blackberrys camera to scan a 2D Barcode on his friends device and all his BBM Pin and other data is transfered through the phones camera so that they can communicate on the service.
I though that this could be used more on android devices. This could be used to transfer small files from one device to another such as contact information, websites (already a reality), even larger files such as word documents and other reletavely small documents. Now i know that these files cannot be displayed on a single 2D barcode but maybe they can be send using not one barode but a series, the barcodes could be in an animation on the device screen, showing one barcode after another all and the "reciever" could simply hold his device's camera over the animation and it could read the series of barcodes and then compile all of the data to create a single document.
Now i realise that this could be a silly idea as the ammount of data that can be transferred through a 2D barcode is not huge, al lot of barcodes would be needed to transfer a larger file than someones contact details.
Let me know what you think, and you are free to do what you want with my idea, i wont hold it against you
