Yes, that's correct. What I do is I change the store folder for the Outlook Express .dbx files by going into Outlook Express and making changes here:
Tools -> Options -> Maintenance->Store Folder
I change it to my "Data" partition, which is drive "E" for me. I do this for 2 reasons, 1. I back up that directory nightly, and also if I have a problem with my OS, I can format C:, reload the OS, then take the fresh copy of Outlook Express, start it up, then point it to my storage folder on my "E:" drive. Outlook Express will ask "There's already storage folders there, do you want to use these?" and bingo you are back in business. The same files can be transfered to another PC and you can follow the same procedure there.....
Good Luck.
