EFS data recovery



Hello everybody, I stored some my important data in an encrypted text
file. Two months ago I gave my PC to my mother and just got a new pc
for me. Before I gave my pc I copied all my data to another HD. What
happened is that my encrypted folder also remained encrypted on the
other HD and now I can't read the files. So... the only way is to get
that certificate from my pc that was used for encryption. But I'm not
sure if I reinstalled windows on my pc before I gave it to my mother.
If I didn't then it'll be easy to recover that certificates. But in
case if I reformatted my hd the only possibility is that I can somehow
extract that certificates from the local copy of the data that I have.
Basically, I have copied that user folder located in C:\Document and
Settings\my_user_name". How can I recover the certificate files from
that what I have, are they located in user folder?
thanks
.
