The toolkit enables you to choose a different location for the storage files, and you can limit the size of the storage. This is useful if you wish to test your application’s behavior when a small amount of persistent storage is available.
To adjust the persistent storage settings, choose Edit > Preferences... and click on the Storage tab. Enter the name of the directory you wish to use for persistent storage. You can only enter a relative path, and the directory you specify is created in the {toolkit}\appdb directory.
If you wish, you can enter a limit in kilobytes for the size of the persistent storage. Bear in mind that the storage implementation has some overhead in addition to the space your application uses. For example, if you enter 8 kB for the persistent storage size, 8192 bytes is available for both your application data and the storage overhead.
If you wish to erase the persistent storage of the emulator, choose File > Utilities...
from the KToolbar menu. Click on the Clean Database button to wipe the persistent storage clean.
