Adding Columns to Windows Explorer

I know this is a Revit MEP Blog but someone asked the question today "how do I add colums to my Windows Explorer so I can see who edited a file last?". I figured others could probably use this (I certainly will...).

1) Go to Windows Explorer
2) Right click on the column headers and select "more"
3) Check "Owners"
4) Go to Folder and Search Options and select the "view" tab
5) Select "Apply to Folders"

You will now see the user name for whoever edited the file/folder last! There are probably other usefull column headers but I didn't explore it any further.
