I right-clicked on a file and opened "Properties", then I clicked "Advanced".
On the pane that opened I selected "Encrypt contents to secure data", I think
I then waited for the files to be encrypted. Along the line the files were
copied to another disk. Since I have re-installed "Windows Vista Ultimate".
How do I open these files?? When I try to "decrypt" them I get flashed with
an error saying "Access is Denied". I want to enter an encryption key, but
where do I put it? Other people do this. Thanks!

"What to do if you lose your file encryption key

If you try to open an encrypted file and you get a message that access has
been denied, your encryption key might be corrupted or missing. In this
case, you must have a backup copy of your encryption key, or, if you're on a
domain, your network administrator must have a recovery certificate. You can
recover the encrypted files by restoring the encryption key with a backup
copy, or by using a recovery certificate. If you don't have a backup copy of
the key or a recovery certificate, you won't be able to access your files.

If you are connected to a domain, it is possible that a network
administrator can restore your key.
