How to Turn On File Extension in Windows 7

In Windows 7, files are displayed in the Explorer with their names only. If you want to know what the file extension is (for example, doc is the file extension for a Microsoft Word document), then you need to change some settings first. Here is how to do that.

While you are in Windows explorer, click on Organize on the top left of the bar followed by Folder and search options from the drop-down menu.

A Folder Options dialog will appear. Click on the second tab named View to see a list of Advanced settings for the folder, as shown below. Under the Advanced settings, look out for the Hide extensions for known file type. Uncheck the checkbox next to it and click OK.

The files in the Explorer will now display with their extensions, along with the file name that was already displayed previously.
