Total Commander

Deleting files with many files and directories takes a lot of time, because totalcmd at first is counting how many files and directories are to delete. If there is a lot of files than I must wait when it finishes counting, so is it possible to count it on fly and delete files which has been already counted up?

TC allows to abort counting by pressing Escape. Also you may disable counting before copying/deleting in configuration (Configuration - Operation, Calculate space occupied by subdirs...). Unfortunately if you disable this option TC will not show second progress bar for copy/delete operations.

BTW idea to count files in low-priority background thread sounds great.
