.wexe extension???

I don't know how it happened, but all the files in my thumbdrive now has this ".wexe" extension. I can't seem to open any of these files. Anyone knows how to open these files?
I'm still hoping for a 'saviour' to help me retrieve these corrupted files....

If not, i'll have to delete everything.
:(
