Is there anything like a link or shared mount point for FAT32 folders in Linux/Android?

Solution 1:

It is possible to mount a folder in another folder if you have root.

open adb or terminal (adb is preferred) and type

mount -o bind /origdir /newdir

This should have the same affect as ln and will work on FAT32 filesystem

Solution 2:

Endolith answer is best for your situation, but Sathya is wrong, there is also solution, if you really need to fake link(hardlink), see: https://stackoverflow.com/questions/4545536/faking-symbolic-links-on-a-fat32-formatted-storage Though i hadnt tried it on android.

Solution 3:

FAT doesn't support symlinks.

Is there a way to make two different folder paths on a FAT SD card point to the same file

No.

Can FAT be extended to support them

No.
