Sort files and folders alphabetically in file picker

When browsing through the file system in the “Create new backup” or “Restore” wizard, files and folders are displayed unsorted.
Files and folders should be sorted alphabetically (folders at the top of the list) for easier navigation.

Yes, that should be done (and easy to do).

While personally I agree with you on the “folder first” sort order, don’t some Linux flavors go strictly by file name (and some sort by case as well)?

If so, should this be an optional or local environment based setting?

I would also like to see folders listed before files, but even more so I would like the sorting to be case-insensitive (not all uppercase before lowercase). Is this possible?
