oops - user accidentally deleted profile

Try Recover 98 Express from

http://www.lc-tech.com/recover98%20network.asp (be sure to remove any spaces that might have crept into that address). It can be run from a floppy disk so you won't need to fear copying it to the hard drive.

Be sureto STOP using that computer until you can run a recovery program on it or you risk overwriting the deleted files.

Unfortunately, there won't be a lot to recover.
When something is deleted in Windows, it moves to the recycle bin. This process garbles up the file name. When the size of the files in the bin exceeds a certain size (f.e. 10% of the HD size), the oldest files are purged. Forever.
I can imagine that a profile is larger than the trash can. So by the time the last files are moved to the recycle bin, the first are already gone.

Maybe a silly question: do you have a backup? If not, you'll soon find out that a backup solution is much cheaper (in terms of Total Cost of Ownership) than a recovery solution.
