[Q] External SD Card direction

I cant seem to get files from external sd card within some programs.Like psx4droid or FPse.When it comes to select bios,it shows me a file browser.There is one folder "sdcard" but its the internal sd card and i cant find the directory for the external sd card.
yeah,yeah,10 gb are a lot of but i want to use my sdcard too
Samsung have moved the location where it's mounted to and some apps which are hard coded can't find it.
If you can go up a directory from sdcard to mnt you will then find extSdCard containing your ROMs.
yeah,my bad.i found it!
thank you very much

How to swap internal memory and SD Card

I have a custom-made rooted MTK6575 based phone, and it has internal storage of just 127MB and an external SD Card of 8Gb.The Phone spec is 512MB
I want to swap these two and tried all the ways I found from the forum such as
a. Modifying the vold.fstab and vold.fstab.nand
b. Trying out External 2 Internal with Universal Init
Both did not work out.
Upon check the /mnt folder, I realised that there is only one sdcard folder. The internal memory of 127MB seems to be shared with the 512MB and there is no mounting script that I can find.
The only effect I have gotten is from modifying the vold.fstab.nand file. If I change the sdcard to sdcard2, my sdcard will not be seen under storage and only the 127Mb internal storage will be seen.
Anyone can help ? :crying:

Windows can't access internal SD and cropy and paste files anymore

I just installed CM11 and formatted the internal SD in CWM. However I can't copy and paste files into my internal SD card anymore. There's no files in the internal SD either. I already tried formatting formatting the SD card in default format but no luck. How can I regain access to the internal SD card and make everything work?
Anyone help please?

Sd card as default storage for device folders

Hi guys, good day to all.
I have a trouble with my sdcard that can't be set as default storage for my device folders such as Screenshots folder, documents, downloads etc.
I've tried moving them from internal storage to sd card and yeah it worked. It changes to sd card but when i try to do screenshots, still not going to the folder i've moved in sd card, it's just creating another folder and default storage is internal.
Is there other ways to set the sd card as default storage for my folders from internal storage?
Thank you again guys for the help
My device is Samsung A10s running Android 10
If the external SD-card is formatted with a filesystem your phone can handle and if phone's Android is rooted you can try to create related symbolic links, as you you can do it in Windows OS, too.
Synthax:
Code:
ln -s /path/to/folder /path/to/link
