I've seen a suggestion to change a file's modification timestamp with the copy command:
>copy file.ext +b
Is there a way to do this on a XP machine without copying or external programs?
Edit: I asked the question because my mp3 player irritatingly lists files by modification stamp. This is what I ended up doing:
>dir *.mp3 /b > dir.txt >for /f "delims=" %f in (dir.txt) do copy "%f" +b >del dir.txt
