Kept((( prompt ?
I'd not be hopeful. You could try searching your drives for part of the file name, or get it to search in files for something you know should be in there.
There are decent recovery programmes about, if you are desperate. Trouble is recovered files with data, a single corruption can mess up the whole file, even if found. If you do use a recovery programme remember to install it on a different drive so that you don't overwrite anything.
