MSMount allows you to access Palm applications and databases that are on the Memory Stick or SD card as if they are on the internal storage. With MSMount, an application that does not support VFS can access the Memory Stick or SD card. You can also move large databases (e.g. dictionaries) from internal storage to the Memory Stick to free space.
MSMount can be enabled or disabled for individual applications, in case certain apps are incompatible and cause crashes.
Note that MSMount does not support Palm OS 5! For these and other devices, see PowerRun.
