where Android stores files - Android Q&A, Help & Troubleshooting

Good morning,
I think that somehow this thread could be related to:
http://forum.xda-developers.com/showthread.php?t=1304192
but I have a different main question.
Where Android store files? Or, to be clearer, what kind of files are saved on the:
- internal flash (is it a flash? am I right?)
- internal sd
- external sd
The clockworkmod backup what really back up? only the internal flash?
If I'd want to change the rom I use on my lg 2x, from djdroid based on froyo to cyanogenmod based on gingerbread, what if I:
- choose all the 3 swipes from recovery
- format the internal sd card (is it really needed?)
And, most important, if I'd like to completely restore the previous situation (that is, not only the rom, but the settings and data..), is it right the procedure:
- choose all the 3 swipes from recovery
- format the internal sd card
- restore a previous backup with recovery
- restore the content of the internal sd card using a previous backup on my pc (is it really needed?)
Thank you very much, any help or clarification would be really appreciated.

E.g. Galaxy S 2
-internal storage (store system file)
-internal sd (store music)
-external sd (extend to stores music files)
I am using a phone without external SD. What I know is internal storage is storing system file, e.g. apps, data, system, that similar to windows system32 folder.
When you are using clockworkmod backup, normally those backup are stored in sd (external if available). For my situation, it is being stored in internal.
Clockworkmod backup EVERYTHING in your internal storage (not sd), form data, game, cache, or anything in system.
If you are going to restore, it will ONLY restore internal storage and not internal SD.
If you wanted to confirm where those backup clockworkmod files are store in, just go into any file explorer and check ClockWorkMod/backup/(folder with date).

Multiple SD card partitions (Coming from Droid X)

Hi guys. I received my DX2 as an upgrade from the DX. Now I have sdcard and sdcard-ext. This is really throwing my app setting into disarray. For example: when I attempt to do a backup of my go launcher ex settings it will backup into sdcard-ext (i believe) but when I try to restore it will only do so from an older backup from sd card. How can I bring order to this??

The Big problem is MOTO calls both internal storage & externel
storage sdcard. (sdcard& sdcard-ext)Then throw in a CD-rom
partition (part of internal storage) & and you have a perfect
storm leading to lots of confusion.
Our phone has the following, according to VZW and Moto:
- 8GB of internal storage. This breaks down as 2 GB secure memory and 6 GB of usable memory.
- 8GB of external storage which refers to the removable SD card behind the battery.
In the 2 GB lives the Android system files and installed applications with most of their associated data. Some programs are accustomed to using the "sd card" which I will get back to in a minute. You can look at the status of this 2 GB in 2 different ways: 1. Settings - Storage - Application storage, "Available Space"; 2. Settings - Applications - Storage Use - All - Application Storage (on the bottom of the screen).
The 6 GB can be viewed by: 1. Settings - Storage - Internal Storage; 2. Settings - Applications - Storage Use - Media Area.
When you move things to the Media area, you are taking a portion of the installed app from the 2GB and moving it to the 6GB, which is similar to the way in tho older phones, you moved apps to the SD card. So, the question is why do we move apps to the SD card? In older phones there was far less "internal storage" and you would literally run low on memory for apps. New phones have much more space, so unless you are installing lots and lots of apps, it shouldn't be a problem.
With our phone, they have included internal, hard wired, SD Card-like storage, which can be used, mounted/unmounted, just like an external SD Card. The Media Area is simply a folder on this remaining 6 GB area. In some cases, this is automatically done by some apps, for backup purposes or caches.
Hope this helps
The issue is that since I'm using the SD card that I used for my droid x I seem to have 2 partitions on it. One that was created by the DX2. Now half my apps think that the old dx partition is where they should put data. So how can I merge the two so that my entire SD card is 1 entity?
So my setup is currently
internal 2gb/internal storage/sd card (dx)/sd ext (dx2)
corz123
I would just connect phone to computer copy
everything from sd-card to computer.
Then delete, format sd-card, copy
everything you need back to sd-card.
Hope This Helps
hi that sounds like a good idea. so if I do that will it be formatted as sd or sdext? i read some threads that mentioned that if its sdext (dx2) that some apps wont be able to detect it or save settings.
also i'm using a rom (eclipse) does that make a difference?
corz123,
It will be the ext sd-card. Motorola calls the Internal storage
sd-card and the removeable 8gb card ext sd-card confusing I know.
(See my previous post)
You should avoid loading programs on removeable sd-card (ext sd-card)
I only put picture's, movie's, music, and doc's etc on removeable sd-card.
Most program's won't work very well or not at all when loaded on ext
sd-card.
Hope this Helps.
Use the thanks button when someone helps you. (ITS FREE) and Its just nice to see
did motorola change their setup? I had a droid x and i don't believe the used the sd-ext convention.
corz123,
Get a file manager if you don't already have one
such as Astro, ES File Explorer, or Root Explorer if your rooted . Open
whichever one you have or acquire and U will see sdcard sdcard-ext.
Ok see you later

Confusion about SD-Card in Samsung Galaxy SII

Hello All,
Just got a white one without any external SD-Card (the micro SD) installed. I was able to root it using the CF-ROOT V5.0 guide which is an excellent resource for noobs like me.
Using the CWM (which shows in the applications menu after the root) I was able to take phone complete backup.
Now the confusion begins that even though there was no external SD card installed the backup took place and then it was saved in
Code:
/sdcard/Clockworkmod/backup/folder_name_date_time
Infact /sdcard is the home directory to start with, which is shown when I browse files using the built-in file manager called "My Files".
So when is there is no SD-Card installed, why is the internal home directory called SD-Card , where the nandroid backups are saved automatically ? (i guess the internal storage is also called SD-Card, is it so ? bad naming idea then)
Now I did install a 2GB external SD-card and formatted it using the storage options within the settings menu.
So apparently this (actual) SD-card is mounted in the directory called
Code:
/sdcard/external_sd
Then again I tried taking a nandriod backup hoping that it would automatically detect this available external sd card and would save the backups, which did not happen and the nandroid again took backup to the internal SD storage.
So how to direct nandroid to take and place backups on the external SD card.?
Secondly I have also read about the Sd-Ext partition, can someone please explain what is this partition , how is it made, and what is the benefit of using this partition. Can i make it a default location for installing application and what other uses can I have of an SD-Ext partition.?
Do i need App2SD and Link2SD in order to use SD-ext partition for any purposes.?
If I take a backup again using nadriod would it place it on the SD-Ext partition or the left over space in the regular SD card partition. ?
Thanks a lot for reading and clearing up my confusion mentioned above.

Thanks again.

[Q] Format internal SD

Hi
I want to format the internal SD card, (phone memory), as I feel my phone is getting a little slow while copying files from PC to phone.
What precautions should I take? I hav made a nandroid backup, and Titanium app + system backup. Should I manually make a copy of the folders on the internal SD card on my PC, and restore them to internal SD after format?
yes copy to computer
then reboot into recovery, choose wipe data / factory reset

[Q] Error mounting externalSD on CWM on SGSIII (i9300)

Hi,
Three weeks ago I had my SGSIII rooted and with a custom ROM and regular backup in the external SD card and everything was working OK.
I wanted to remove all the information form the internal memory and decided to format the internal memory, so using CWM (6.0.4.7) I made all the wipes and formatted:
/system
/cache
/preload
/data
I think that one of those formats was the source of the error, but I don't know which one!
Afterwards I tried to access the externalSD card from the restore menu to restore one of my NAND backups, but the extrenalSD card was not accessible (E: Can't mount /storage/sdcard1) neither from the install zip menu (same error). the SD card was OK because was workable in another phone. I tried to mount the external SD card from the mounts and storage menu but gave an error (Error mounting /storage/sdcard1!)
Since I could not restore my NAND backups, I restored the stock ROM (JB 4.3) using odin and afterwards I rooted the phone and install again CWM (6.0.4.7) but the problem persisted and now I am using the stock ROM and can access the external SD card from android normally.
I have looked about this error and all the cases I have found are using older versions of CWM and recommend to format the external SD card, so I did, but the problem persisted.
So my questions are:
- What have I done wrong?
- How can I fix it?
Afterwards I thought that I could copy the NAND backup from the external SD to the internal memory so I made NAND backup to see where it was stored, but using ultra explorer I cannot find the location (furthermore, according to the DiskUsage App the space is used but does not inform me where it is).
I have asked Google for the location of the backups in the internal memory (I can not recall such locations) but the folders did not exist or where empty. So:
- Is it possible to copy a backup from the external SD card into the internal memory?
- How can it be done?
Thanks in advance for your help and sorry for the lengthy post.

TWRP cannot backup internal storage?

I was looking up the release notes for the new version of TWRP, version 3.1.0.0, and noticed that one of the changes listed was:
better indicate to users that internal storage is not backed up (Dees_Troy)
I am confused, I thought if you checked every partition when backing up, it basically backs up your entire NAND? If not, then what is the data partition for if that's not my internal memory? Since my backup was around 22-23 or so gigs uncompressed, and my phone is a total of 32 gigs with about 8 free, I assumed it was just backing up everything.
If not, then what is on this partition that TWRP won't be backing up? My application's settings/data and any personal files are what I care about, and I assume those are in the internal storage? Or are they in the data partition?
Do I have to use something else to backup my internal storage then? Is there any reason TWRP won't (or just can't) backup internal storage?

Hi
Internal storage won't be backed up, TWRP can backup (system, data, cache, boot, preload, efs) partitions to the Internal storage or the external storage, so the internal storage is the PATH of the backup, not a part of the backup, to backup the internal storage, you simply copy the files from the phone to your PC or your Laptop through MTP
Apps and OS and apps' data(except for files in /android) is available in System and data partition
Photos, videos, music other personal files you download or copy from pc to your phone is in the internal storage.
Regards Migo
I'm still a little confused about a few things.
1. If it doesn't back up my internal storage, then why are backups nearly the entire size of my used up memory anyway?
2. Kinda unclear what is on internal storage then if my app data isn't on there, especially since I use a SDcard for my camera.
3. Is there any technical, legal, or other reason why TWRP can't backup internal storage if you are backing up to external storage? I can understand if you are backing up to internal, but not to external.
4. So then if my internal storage just the fake "sdcard" folder that just links back to my internal storage? (Damn do I hate that thing, I have several apps that downloaded hundreds of megs to several GIGS of data that they assumed was external storage, but it was really the emulated internal). If so, what would be a good way to created synced backups? Just simply copying the "sdcard" folder doesn't really help keep files in sync (especially ones deleted since the last backup) nor compresses them.
