How it works
Linking apps and games (Link2SD)
Apps2SD moves apk, odex, dalvik-cache, lib and internal data files into secondary partition on your SD card. 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 (Obb2SD)
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 files into the first/second partition of your external SD card and with the bind option of the mount command remounts the file hierarchy.
Note
Apps2SD detects apps linked using Link2SD. Although obb and external data link by Link2SD/other apps will not be detected.
