How to Show Hidden Files and File Extensions in Windows 11

You need to see hidden files and folders, or you want the extension (like .docx or .exe) to show at the end of every file name.

Why: Windows hides system files and the extensions of known file types by default to keep folders tidy and prevent accidental edits. Both are simple on/off switches in File Explorer. Seeing extensions is also a good safety habit — it helps you spot a file pretending to be a document when it’s really a program.

Fix 1: Turn on both from the View menu (quickest)

1. Open File Explorer from the taskbar (the folder icon).
2. On the toolbar at the top, click View > Show.
3. Tick Hidden items to reveal hidden files and folders.
4. Click View > Show again and tick File name extensions to show endings like .txt and .jpg.

Hidden files appear slightly faded so you can tell them apart from normal ones.

Fix 2: Use Folder Options for more control

If you want extra settings (such as showing protected operating-system files):

1. In File Explorer, click the three dots (See more) > Options.
2. Go to the View tab.
3. Under Advanced settings, select Show hidden files, folders, and drives.
4. Untick Hide extensions for known file types, then click OK.

FAQ

Will showing hidden files break anything? No — viewing them is safe. Just avoid deleting or renaming system files you don’t recognise. To hide them again, untick Hidden items in View > Show.

Why should I show file extensions? It helps you spot dangerous files. A file named invoice.pdf.exe looks like a PDF when extensions are hidden but is actually a program. With extensions visible, the .exe gives it away.

I still can’t see a specific file. Some files are flagged as protected system files. Use Fix 2 and also untick Hide protected operating system files, then confirm the warning prompt.
