Anyway to search for all files with NO extension?

[LongCoolMother]

I know its a strange thing to do. But is it possible? It seems I've lost a file (whose filename I've forgotten) that has no extension. It'd be useful to be able to display all and only files with no extension.

What happens if you do a generic search with *.

Open a command prompt via Start \ Run \ 'cmd', then change to the root of your boot drive with 'CD \'.

Then use:

DIR /A-D /S /B *. >list.txt

This will search all sub-directories and output a list of files with no extension, including their path. The list.txt file will be created in the root of the drive. Remove the /B if you want date information. If the file you're searching for is on a different drive, type 'X:' instead of 'CD \', where X is the drive letter.
