Recently, I changed jobs. I had a laptop using Windows XP. The files I copied to a memory stick are fine. However... the files copied to an external drive are encrypted. When I right click, I can see my old login and a 40 digit code. The file size is in tact. Is it possible for me to add my home computer in the "add user." When I do this, I get the message, "The CA root certificate is not trusted" (for my home computer). "To enable trust, install this certificate in the Trusted Root Certification store." HELP ! ! ! Is this as simple as adding a CA root certificate and then removing the encryption? Your brilliance would be appreciated. These are small Excel and Word files in question.
