Total Commander

One of the things I do many times per day is making backup copies of the files I'm working on. The fastest method is Ctrl+C and Ctrl+V on a file, which creates a copy with added " - Copy (n)" in the file name.

I know, it's the Windows Explorer which is part of Windows OS which is doing it and it has nothing to do with Total Commander. I just wish there was a way of doing the same thing using a shortcut in Total Commander for the purpose of being able to customize the file name of the copied file.

I prefer the following format. If the name of the file is "MyFile.xyz", then I usually rename to "MyFile.001.xyz", then "MyFile.002.xyz" and so on. This way when all files are sorted by the file name (or extension as I always have) all files with the same name are grouped together, where the Windows method makes a mess, like:
MyFile - Copy (3).xyz
MyFile - Copy (2).xyz
MyFile - Copy (11).xyz
MyFile - Copy (10).xyz
MyFile - Copy.xyz
MyFile.xyz

Well, you could use Shift+F5 instead of Ctrl+C/+V to create a copy. TC then provides a dialog in which the copy's name can be entered, with the name (without extension) already preselected (if this is set in TC's configuration).

Not saying you should, but have you considered copying to a backup folder? That way your work folder stays clean and the copies are not in the way so to speak.

I use this https://www.ghisler.ch/board/viewtopic.php?t=80890 setup, and I have it assigned to a button and a user command so I can use a hotkey as well. If the backup folder doesn't exist yet, it is created. You can also leave out the backup folder and just leave T="%P\" to keep it in the same folder.

And perhaps consider using %$DATE% variants to use a timestamp in the name instead of a sequence number. For example:
