Many people will be familiar with the command line tab completion functionality that can be used to complete folder and filenames in recent versions of Windows, but what I wasn’t aware of (until I just used it, following some instructions from Microsoft in a hands-on lab training manual) was that wildcards like *.reg <tab> can be used to tab-complete filenames. This technique can even be used as arguments to a longer command, e.g. notepad *.reg <tab>.

Dustin L makes a good point in his comment on the Lifehacker article that discusses command line tab completion – Unix admins will already be familiar with the concept but there are a couple of differences between the Windows and Unix/Linux CLI tab completion implementations:

• “In the Windows command line, if there is more than one match for what you’ve typed, successive presses will cycle through all of the matches rather than just display a list of the matches.
• Windows will not complete commands, only files and directories.”
