Hey seshu.vnkt
Thanks for the reply.
I think u didn't get my requirement. In my file name i have first couple of characters same next set is different and last set has date (which will be the current date).
So I want to have "dtc___<<current Date>>.txt"
the blank line is of 3 characters which could be any but the first and last set will be same.
Thanks.
Gunjan.
