Linking applications



Link2SD uses a secondary partition on your SD card and uses it as another segment of internal storage. Link2SD moves apk files, dalvik-cache (.dex) files, lib files and internal data files into this partition, which the OS mounts on boot, and creates a symbolic link in the original location. This retains the file structure that the system expects but with the bulk of the data moved to the SD card. 

Linking obb and external data;

On devices that have emulated SD card, obb and external data files are actually located on the internal storage, not on the external (real) SD card. 

This method moves these folders into the first or the second partition of your external SD card (depending on your selection) and with the bind option of the mount command remounts the file hierarchy at external SD card while it is still available at the original location. 

 

link2sd aparted apps are marked with "Linked -> SD card" in the app list.

 

What you need:

Linking apps;

- root permission

- second partition on SD card

 

You should have two partitions on your SD card and both should be primary.

The first FAT partition is your standard SD card storage. The second partition is used for application files and can be ext2, ext3, ext4, f2fs or FAT.

You need to use a non-FAT file system (ext2, ext3, ext4 or f2fs) on your second partition in order to link app\'s private data files. Because the FAT file system (FAT16, FAT32 or exFAT) does not support UNIX file ownership or permissions and will cause a security breakdown of app's private files.
