Can't Find My .FLV Videos With Recuva

I had deleted about 30 or 40 flv videos earlier today. I tried to get them back minutes after deleting them with Recuva and it didn't find any of them. It found all sorts of useless files. files that ere k/b in size. and files from many months ago. Does Recuva recognize .FLV Videos and why didn't it show up when I scanned right after deleting them? I really need to get these vids back.

Recuva does support flv files.

How did you delete them, through the recycler, or shift/del, or some other way?

Did you run the wizard or in Advanced Mode?

Did you download and install Recuva after the file deletion?

Did you run a normal or deep scan?

Did you specify any search criteria?

Is the partition FAT or NTFS?
