I installed Q-Dir and like it a lot.
at one point I got it to show the "Folder Size" column . Now I can not figure out how I got that column to show on the other computer.
that might help you?
How did I get these options on one computer but not the other computer .…it looks like the one on your page.
"Q-Dir" takes everything from the operating system!
On one computer is probably the freeware FolderSize or DirSize installed!
Install the same same software on the second PC.
I hope I could help.
