Do you want to delete a file on the desktop or on the device?

On Device..

What I want to do, as I install first release of my App.
I made coding changes also made Database changes and made updated release.
While installing updated release I have to use new database, that's why want to delete old database file which is on SD card of Device.

Hope you understand my issue.

When you run the program you can check if the file does exist and :
If yes :
- Either delete it and copy the new one from DirAssets.
- If you have a version in it, check the version and delete and copy the new one if needed.
If no: Copy the file.
