How to Show File Extensions in Windows 10

by

In Windows 10, file extensions are hidden by default. This may cause confusion after a fresh installation, as file types like .exe, .pdf, .jpg, or .zip are not clearly visible. Showing file extensions improves file control and helps identify potentially unsafe files.

Method 1: Show file extensions using File Explorer (quick method)

  1. Open File Explorer.
  2. Click the View tab in the top menu.
  3. Enable the option “File name extensions”.
  4. File extensions will appear immediately.

Method 2: Show file extensions using Folder Options (classic method)

  1. Open File Explorer.
  2. Go to View and click Options.
  3. In the Folder Options window, open the View tab.
  4. Uncheck “Hide extensions for known file types”.
  5. Click Apply, then OK.

Quick summary:

  • For the fastest solution, use Method 1.
  • For a permanent system-wide setting, use Method 2.
  • Keeping extensions visible improves security and file management in Windows 10.
