Re: Can I create different files with looping ?

The issue can be worked around several ways. 
It occurs because %random% is parsed only when the loop is started - so it remains fixed at one value within the loop.

In the way you are using it this will work, but it can still fail on a file because the %random% variable can duplicate the same value in any given series of numbers.

@echo off
for /L %%a in (1,1,10) do call fsutil file createnew %%random%%.bat 100
pause
