How can I de-crypt a folder/file after I re-installed Windows XP pro.?

I encrypted the folders then transfered it to a different internal hard drive. Did a clean install of Windows XP pro w/SP2 then tried to transfer them back to my documents in the C: drive. Keep getting a error, access denied. Went through microsoft support, took ownership, still cannot gain access to them. Please Help. Thank You

First decrypt all the files or folders with the same software by which you have encrypted it %26amp; than try to move files %26amp; folders. Please don't forget to install encryption softwre.
If I were you, I would decrypt those files using the software which I used to encrypt it.
I could be mistaken but I belive that XP encrypts user files to a particular user profile. If you reinstalled XP, then You probably lost the encrytpion key specific to that instance of the user profile. I believe there may be MS certified technicians that have the tools to decrypt EFS encrypted files. Good Luck
