That was not what the OP asked - he asked how.

Asking in a Cygwin group implies he is looking for a Cygwin solution to a 
problem someone created with Cygwin utilities.

I doubt anyone has bothered, so some background info to do the job is referred 
to, and illustrated somewhat.

The easy Windows answer is open Explorer on your 'Recycle Bin' and select 
'Restore' after selecting all those files deleted by mistake.
