The Windows 7 operating system, which was released in July of 2009, offers a lot of different options and settings that one would expect from a modern operating system.

You are probably familiar with the way that Windows 7 organizes and displays your files and folders. The most common way to view this information is with Windows Explorer.

Windows 7 will, by default, hide the extension of a known file type. In many instances this is perfectly acceptable, but you may find yourself needing to modify the file type or extension, or you may need to identify a specific file when multiple files share the same name. You can modify this setting in the “Folder and Search Options” menu.

The steps in our guide below will show you where to adjust the setting that controls whether or not file extensions are displayed for the files that you see in Windows Explorer.

So if Windows 7 is currently only displaying the names of your files without the extension that lets you know what type of file it is, then the steps below will show you how to make that adjustment.

How to Display File Names in Windows 7

Note that, by choosing to display file extensions in Windows 7, you are opening yourself up to the possibility of accidentally changing the file extension for that file as well. A file with the incorrect file extension will usually not function properly, so it is best to avoid editing the file extension unless you are certain that you wish to do so.

Step 1 – Click the “Windows Explorer” icon in the task bar at the bottom of the screen. It is the folder icon.

Step 2 – Click the “Organize” button at the top-left corner of the window, then click “Folder and Search Options.”

As mentioned earlier, enabling this option gives you the ability to modify, or even delete, file extensions. This can corrupt the file, making it unusable. Often this can be resolved by simply restoring the file type extension, but it may not always work.

If you are only enabling this setting because you need to perform a specific action, then it might be a good idea to follow these steps again when you’re done and choose to hide the file extensions again.

You can search for files or a specific type by clicking in the search field at the bottom of the screen, then typing “.file-extension” but replacing the “file-extension” part with the type of file you are trying to locate. For example, if you wanted to find PDFs on your computer, you could do so by typing “.pdf.”
