I'm translatig all the names from a finnish version so they definately will
not match 100%, but the idea should be farely close.
Windowsbutton + E (resource manager
Tools -> settings of the folder
Show -> Here you should find a long list of checkboxes. Near the end of the
list there is something which says "hide the extensions of known filetypes".
Try that one.
