How it works:
Linking apps
Link2SD uses a secondary partition
ONLY FOR ROOTED DEVICES
on your SD card and uses it as another segment of internal storage.
Link2SD moves apk, dalvik-cache (.dex), lib 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.
