Can I convert .qb2007 files to .qbb format.
Converting QuickBooks 2007 Files directly to QuickBooks Backup Files (.qb2007 to .qbb conversion) should be possible and quite straightforward.
Use the 'File -> Backup to QuickBooks Windows' function in QuickBooks for Mac. Make sure you don't overwrite your existing data when restoring older backups.
