Just an FYI for the original poster.
For just one line the time difference is fairly trivial. Dave's code is still faster but not by much.

But if you wrap them in a FOR /L and make each set of code execute 10,000 times, Dave's code is considerably faster. We are talking by several minutes.

The CALL slows down Yury's code. Also you would not be able to use Yury's code if your input file had more than one line in your input file.

This is all you need:

@echo off
for /f "usebackq delims=" %%a in ("a.txt") do echo %%~xa

Not quite That includes the unwanted dot from the extension. That is why I have an extra loop.

yeah, good point.

One more way: .

@for /f %%i in ('cmd /u /c type "a.txt"^| more^| findstr [0-9]') do @<nul set /p=%%i

.

This assumes numbers never appear anywhere else in the path - probably not a good assumption.

thank for all!!
