How to copy files names without extend name?

See here:

[Commands to copy selected filenames to the clipboard)

[ul][li]If you mean you just want the file names (no paths) then use:

Edit -> Copy Filenames -> As Names Only

Or you can use this command:

Clipboard COPYNAMES=nopaths
[/li]
[li]If you meant you want the short file paths (8.3 names) then use this command:

Clipboard COPYNAMES=short

You can also combine the two, to get just the short (8.3) filenames without any paths:

Clipboard COPYNAMES=short,nopaths
[/li]
[li]If you want the names to be on a single line, instead of one line per name, then add single. For example:

Clipboard COPYNAMES=short,nopaths,single[/li][/ul]
