Version: (using KDE 4.3.4) Installed from: Debian testing/unstable Packages In the dialog when you will overwrite a file in a move or copy, will be very usefull if you can compare the md5sum or other hash to see if the file are the same or not. Maybe a more complex method of comparison is possible. For example, compare two PDF files and inform which page differ in a vimdiff style.
