**How Link2SD Works:**

Link2SD leverages a secondary partition on your SD card to extend your device's internal storage. It moves APK, Dalvik-cache (.dex), LIB, and internal data files to this partition, which the OS mounts during boot. Symbolic links are created in the original locations, preserving the expected file structure while moving the bulk of the data to the SD card.

For OBB and external data folders (on devices with emulated SD cards), Link2SD moves these folders to either the 1st or 2nd partition of your external SD card (depending on your configuration). It then uses the `mount` command's `bind` option to remount the file hierarchy at the external SD card, ensuring the data remains accessible at its original location.

**Requirements:**

* **Linking Apps:**
* Root permission
* Second partition on the SD card (primary, non-FAT file system like ext2, ext3, ext4, or f2fs)
* **Linking OBB and External Data:**
* Root permission
* Second partition on SD card is optional.

Link2SD also supports the native App2SD feature of Android, allowing you to move user apps to the SD card (force move) with batch processing capabilities.
