Memory Card Support

Apt supports applications on external memory cards. This is sometimes called VFS support, where VFS stands for Virtual File System.

To enable VFS support, you need to set the checkbox in the Settings form. However, that will only be possible if your device actually supports external memory cards.

When VFS Support is Enabled

  • Apt will include VFS apps on the card in the target selector. They are marked with a yellow background to differentiate them from the apps in the device's internal memory.
  • VFS apps can be launched via the 'App' action. To launch a VFS app, Apt will first copy the application file from the memory card onto your device. When you leave the VFS app, it will be deleted from the device's memory (but still left on the memory card of course). If a reset occurs while running a VFS app, Apt will attempt to delete the file from the device's memory once the reset has completed.

Note that when the app runs, it may create several database files in the internal device memory. These are not deleted by Apt.

  • everything else functions as for normal apps, with the exception that Hiding and Backup pulldowns (Prefs+ screen) are not functional.


  • Apt only looks in the directory PALM/Launcher on each external memory card.
  • DAs and Panels on an external memory card cannot be launched.
  • The number of apps which can be included from external memory cards is dependent on the lengths of their names. Two or three hundred should be OK, though Apt's loading may be much slower and some other operations while Apt's UI is not loaded may also be slower (untested).
