Notes & Limitations
- Generally, external SD cards are usually much less reliable (especially certain device/SD card combinations) than internal memory.
- The SAF API provides much lower performance than standard direct file access mode (especially with directories containing many files/subdirectories).
- Home/Custom directories cannot be set in SAF; however, the last-picked SAF URI is automatically saved: Home Button → Go to Last Picked SAF Dir.
- The wipe feature does not work. If the “Wipe after Encryption” option is checked in settings, files will only be deleted.
