perlCrazy,

Did you use Super Search before posting? This question is asked from time to time. Nodes such as Copy spanning multiple DVDs should help you. Please read the PerlMonks FAQ and How do I post a question effectively? if you have not already done so. Your node title 'Need some idea on this' could be a lot better.

Update: Added links to PerlMonks FAQ and How do I post a question effectively? along with supporting text.
