Wildcard * does not include extension when renaming and copying.

[white]

This topic is for reference and discussion.

If you use the wildcard * for the filename when renaming/inplace renaming/moving/copying files, the filename extension is cut off.

This seems to be a leftover from the MS-DOS era before long filename support. I tested it with MS-DOS 6.22 and using COPY and REN does the same. But nowadays when you do the same in the Windows Command Prompt window (cmd.exe), * means full filename.

Is it still useful that when using * the filename extension is not included? Should it be changed or kept for compatibility reasons?

For me, yes.
There are many cases in which a group of files need new names.
But why should the extensions changed ?
The files don't change their type, only in rare cases.
