I've just created a new version of my GUI for the Windows Robocopy command.
Robocopy is a little-known Windows utility that performs a smart copy of the contents of one path/folder to another. By "smart", I mean that it only copies those files that are new or have changed. I use it to backup my files to an external USB drive.
It is available from GitHub here:
https://github.com/ad1mt/RobocopyWinThere already exists a GUI, which I used in the past, but it has bugs. The main problem is that it fails if you attempt to copy/backup an entire drive (top level folder) to another drive (top level folder) .
