I guess it is. I did a deep scan with one undelete application (it was scanning my hard drive for a couple of hours and found nearly 50k deleted files!) but the folder was not found. I've already started building it all over again, I just lost a few hours of work.
However it still seems weird to me. I mean, the database was saved locally, it was in my hard drive in a specific folder. If I had deleted that folder from the windows explorer it would have appeared in the Recycle Bin. When I deleted it from phpMyAdmin it was completely gone, no traces left behind in the hard drive, not even when I tried to find any using those programs. Like it never existed. Any ideas on that? I'm just wandering.
