OE6 uses .dbx files, while OE-Classic uses .mbx files. I don't know what's different about them, but I don't think you can do a straight drag-and-drop replacement.

OTOH, OE-Classic has an "import-from-OE6-store" function, which I think you should be able to point to the store on your thumb drive and import from the dbx files.




Easily found by opening Help->Firefox help from within FF:
How do I set up Sync on my computer? | Firefox Help

BTW, FF also has a built-in Bookmarks backup/restore function, so you can backup your bookmarks to a file and restore them to FF on the new installation.
Awesome! Thank you so much! :)
