A newer app with completely overwrite the older app provided they have the same PRC file name. Thus there is no need to delete an older version of your app. Data is a different matter. If you need to delete an older DB in lieu of a newer format, just installing the new file (again, as long as it has the same name as the original PDB file) will overwrite the old one. If you have a different PDB data file that will not over write the old one, then have your app look for and delete the older PDB every time it starts up. (or you can be slick and have your app respond to the post-hotsync or reset message and delete your older data file only during that time)
If you are using some 'custom' serial app to receive the new file (not hotsync), pass the new file through the exchange manager (as if you were beaming the file). This will enforce the same rules as if you had performed a hotsync and installed the file that way. ----- Original Message ----- From: "M.
