Hi
I have some folders that i Encrypted with the windows built in EFS encryption (right click - properties - advance - Encrypt).
since than i ReInstalled Windows OS (without reformatting. i still have all the system files)but now i cant open any of the files.
at the moment, i want to move the files to a new computer. How can I move these files without loosing the ability to read them in the future?

If it is loaded with Vista you need to decrypt the Files before you transfer them as Vista [b]Can Not[/b] read that Encryption Method. You also need to follow M$'s advice on Backing up the Encryption Key

However if when you reinstalled Windows without Formatting you didn't have a Backup of the Encryption Key you destroyed the original Encryption Key and will be unable to recreate it so these files will remain unreadable.
