I have a Palm DT 6.2.2 on my W7 64 bit notebook and a Palm DT 4.2 on my most recent past XP notebook. I'd like to copy the data files from the 6.2.2 onto the 4.2 by a copy and paste of applications (date book, contacts, memos). I tried copying the folder containing all the applications and something went wrong. I see the two use the same files names and extensions, e.g., Datebook.mdb so I assume the data bases are compatible. Maybe there are some differences between the two DTs t the aggregate level, if that is the case I think I should be able to past over the individual applications...may try and will report if successful. What I am about here is moving my Palm DT operation back to the XP computer while I await some improvement in the W7 64 bit driver environment.
