Windows' Save As dialog can be a little annoying. If you want to use a certain file extension, you have to pick it from a long list, and sometimes it isn't even available in that list. Reader Java-Princess shares an awesome shortcut for saving files with whatever extension you want.
Take Notepad as an example:
Do you get annoyed when you want to save something in Windows Notepad with an extension other than .txt (like .sh or .conf) and you have to use up an extra two clicks selecting 'All files'? Just type in your filename and extension surrounded by quotes e.g. "cart.php" You don't need to hit the combo box and change it and you won't get cart.php.txt when you go looking for the file.
I actually never knew you could select "All Files" and type in any extension you want -- I always set Explorer to show file extensions and replace it from there. Even if you knew that trick before, this is a faster way to get it done! Thanks Java Princess!
