I have lost a file folder from my desktop. I believe my wife was restoring settings or something like that. I have searched for the files and can not find them anywhere. I was able to find a similar file that has not had any added info for the last 6 months but I might have saved it twice. I would like to find the file that I have been using. I do not know a lot about computers, can someone help?

This maybe a silly question, but did you check the recycle bin?

If she used system restore to go back 6 months, you might have to undo the restore and then copy the folder before re-restoring back 6 months. Often people restore to an earlier time to get rid of viruses, but it doesn't work all the time since many viruses use system restore to protect themselves.
