Does anyone know what these files are? They are in my backup directory:

Queries.pdb
Speed1.0_dilP.pdb
BtExgLibDB.pdb
locLCusLocationDB.pdb
Saved Preferences.prc

I fear some are leftovers from past Palms. I am wanting to get rid of the "pork" on my unit.

What prefs are in Saved Preferences.prc? Anything else in there?

What would be the consequences of deleting Saved Preferences.prc and letting a new (upgrade) unit recreate this?

Thanks
