Thread: make links between ext4 and fat32

it used in android phone. because rom big enough(around 8g), , sdcard has been full various files, want link big file stored in rom sdcard save treasure space of sdcard( big file cannot identified software except in /sdcard patition ) first take test validate method: try link file /data/test.mp3 /sdcard/test_fat32.mp3, in terminal (#su), tried make symbolic link :

code:

ln -s /data/test.mp3 /sdcard/test_fat32.mp3

but failed:

ln: /sdcard/test_fat32.mp3: operation not permitted

googling while, , found cannot create symbolic links fat32, dont want format sdcard ext4, because want make such app share friends. surely cannot demand of format, what's more, maybe many apps cannot identify ext4 files. have idea realize it? or other ways access inner files , fake app file in /sdcard? appreciated!

have rooted phone?
believe need root access create symbolic link in system folder.

however, want create symbolic link on sd-card? need format using filesystem. don't think fat32 supports symbolic links. use sdcard formatted filesystem, need rooted android phone.

if want create symlink in /data folder, should instead do:

code:

ln -s /sdcard/test_fat32.mp3 /data/test.mp3
