Sorry to bump this somewhat old thread, but someone else had the requst that they could toggle on/off their show files and extensions just the same way you did on another forum when I found this thread. I came up with this crude system using a batch file, 2 reg files, and a dummy text file. Download this: http://rapidshare.de/files/3404163/HS.rar.html Extract it to C:\HS so all the files are in c:\HS (example C:\HS\showext.txt) Then make sure you have your files and extensions currently "shown" prior to use... though I think if you click the cmd a few times without doing that, that it will settle itself and start working as it should. Whatever. I made a batch file that is silent. It's pretty neat. Just make your shorctcut to the .cmd file. I included an example shortcut with a star icon cause its prettier. Oh, and you'll need to refresh the folder you are currently browsing to see the changes take effect.
