There is/was a hotkey.. I don't find it now, that will filter out all the none selected files.
I got a folder with 4000+ folders and I selected some of them using different filters. so now I got 417 folders selected. I want to view only the selected folders before I delete them. (So that I can check that I have not selected folders that I don't want to delete.)
There was a hotkey for this.. But I can find it now..
