i have plenty of empty directories and i wonder if there's a way to display actual direcory sizes (after some sort of scan maybe) in MC
Press Ctrl + Space on current directory and this will show it size. Also, you can use visual select to apply this command on multiply items.
If you press Ctrl + Space on
.. directory mc will calculate size of all subdirectories in current dir
To see total size of all directories, you can select them all using Inserl key, and see total size at the bottom of the panel
I would use
gt5 for that.
