FileName extensions for address book, date book and memo pad

[LindaIg]

I have been having difficulty synching my new Treo 680 and would like to set up anew. To that end, I would like to save the essential files:
Address book
Date Book
Memo Pad
Archive
from my old Palm.
Many thanks

I fixed the synch without getting the filename extensions. Figured them out after the new install went in. Had to copy the old files over from the old location. datebook.bak, .bak.bak, .dba, .mdb, .mdb.bak.
