How to Show File Extensions in Windows 10 – Guide

File extensions are the three letters that come after the file name on your computer. They’re what tell Windows 10 what kind of file it is. For example, if you open a picture file called “picture.jpg”, Windows 10 will show you the file extension as “jpg”. There are a lot of different file extensions, and they can be used for a lot of different things. Some common extensions are .doc, .xls, and .pdf. Windows 10 includes a built-in feature called File Explorer that lets you see all the files and folders on your computer, including the file extensions for each one. You can also use third-party tools like FileZilla to view the file extensions for any files or folders on your computer. Now that we know a little bit about what file extensions are and how to see them in Windows 10, let’s take a look at three methods for showing them:

  1. Using the File Explorer context menu: Right-click any folder or filename in File Explorer and select “Properties”. In the “General” tab, under “File Type”, click on the dropdown arrow next to “Extension”. This will show you a list of all the available file extension types. Select one from this list and Windows 10 will automatically show the corresponding extension when you view or open that type of file in future instances (for example: if you open a picture again later in File Explorer, it will now show as “jpg”).
  2. Using keyboard shortcuts: You can also use keyboard shortcuts to quickly show or hide all types of file extensions. To do this, press Ctrl+Shift+E (or Cmd+Shift+E on Macs) to open up the “File Types” window in File Explorer. Under “File Types”, click on “Extensions”. This will display all available keyboard shortcuts for showing/h ..
