Sorry about that. The file extension is .xef. Hope I did'nt confuse you.
I'm using an Hp Pavillion,I had the same HP before. I had data transfered that was encrypted using an exf file extension,however the exf files will not allow me to use my password to decrypt the exf files from my old XP version on my new Vista.I think my Vista programming does not understand the winzip code from the XP data. Any sugestions? Changing user properties is a failure also.
