How can I reverse the sort order? How can I number from 100 down to 1?
First of all, change to Expert Mode by pressing F2.

To reverse a sort order just place a "-" in front of the sorting letter.


"n" sorts by name (a-z) and "-n" sorts reversed (z-a).

"en" sorts by extension then by name.

"-en" sort by reversed extension then by name.

"e-n" sorts by extension then by reversed name

"-e-n" sorts by reversed extension and then by reversed name.

These are just examples. You can put "-" in front of every letter you like.
