I use 4.2 version of Palm Desktop. I have been intending to replace it since it is not supported any longer, but quite frankly have never found anything as good!
However, recently when it opened, it had lost about a month of entries in the Calendar and many new Contacts, and ALL assigned CATAGORIES that I use for EVERYTHING I enter in Palm.
I retrived a backup from Carbonite, but I cannot figure out how to OPEN the backup...because that file extension is .dat. However, the Pilot Archive file extension is .dba. I see no .dba files in any of the PALM folders on my computer nor in Carbonite. All elements of Palm (Calendar/Datebook, Names, Memos, etc) have an extension (when exported) of .dat and that's what Carbonite is backing up because, just like me, it cannot see the .dba files.
This is my last attempt to figure this out. I've spent hours to this point. If you can help, I'd really appreciate it.
