Hi Mumit,

Have you ever tried to simply delete files in a large directory with windows, not from any of the GNU tools (directory containing as you say 600+ files, or as I tried myself 5000+). I deleted files using the Win95 explorer facility and it really is very slow itself. I guess one way or another it all comes to the same system call and my second guess is this system Call is *not* optimised.
Am I saying just silly things or is it that we have to accept that as fate ?

See ya,
Al.
