How do you Decrypt encrypted files & folders ?

Firstly, I wish all u forum members are A-okay
Sorry, for not attending the forum ==> study pressure XI-XII standard. Please forgive me all

Just help me out with this one plz ~

I had to format my machine recently (about 2 months back) , its not the issue, and had to set-up Windows XP afresh.
Everything's fine. Just that with my former installation I had encrypted lots of files and folders within a single Folder using XP's encryption feature. It contained lots of my favourite songs and music videos which I had gathered over a long period of time and did not want anyone to tamper.
The Problem: With my current installation I can't open them anymore

Please anyone tell me how to undo this
YOUR FEEDBACK EAGERLY AWAITED

I don't think you can get back your data.... The encryption key probably got deleted with the format... So, there's probably no way to get it back... However, this might be helpful.
