I happened to look tonight at my hotsync log after performing just a daily hotsync and noticed this towards the end of the log:

-- The database for LaunchUninstaller.prc was deleted on the handheld. Moving the backup to the Archive folder.
-- The database for PalmFlashUpdater.prc was deleted on the handheld. Moving the backup to the Archive folder.
-- The database for OsUninstaller.prc was deleted on the handheld. Moving the backup to the Archive folder.
-- The database for VisorFlashUpdater.prc was deleted on the handheld. Moving the backup to the Archive folder.

Does anyone know why the following files databases where delete or what these files are for?

LaunchUninstaller.prc
PalmFlashUpdater.prc
OsUninstaller.prc
VisorFlashUpdater.prc

I didn't delete anything off of my Treo. I can scroll through the last 10 hotsync logs and every sync has this report in it.

TIA
