Hidden folders exist on every computer, and you can make them visible in a few clicks

Your operating system hides certain folders by default to prevent accidental deletion of files your computer needs to run. These folders contain configuration files, system settings, and process data that most people never need to touch. But if you're organizing your files or troubleshooting a problem, you may need to see them. Showing hidden folders is safe — you're just changing what appears on your screen, not changing any files themselves.

The steps differ depending on whether you use Windows, Mac, or Linux. In each case, the process takes less than a minute and can be undone just as quickly if you change your mind.

Key Takeaways

  • Hidden folders are marked as hidden by your operating system to protect system files, but you can view them without any risk to your computer.
  • On Windows 10 and 11, you show hidden files through File Explorer's View tab by checking "Hidden items".
  • On Mac, you use a keyboard shortcut (Command + Shift + Period) or a menu option in Finder to reveal hidden files and folders.
  • Hidden folders appear dimmed or with a different icon on your screen, but hiding them again is just as straightforward as showing them.

How to show hidden folders on Windows 10 and Windows 11

Open File Explorer by pressing the Windows key and typing "File Explorer", then click the result. Navigate to any folder, then look at the top menu bar. Click the View tab.

In the View ribbon, you'll see a checkbox labeled Hidden items. Click it to turn it on. when ready, any hidden folders in the current directory will appear on your screen, usually shown in a lighter shade or with a different icon to indicate they're hidden. You can now navigate into them and see their contents just like any other folder.

This setting applies to File Explorer going forward — once you check "Hidden items", all folders you open will show hidden files and folders until you uncheck the box again.

How to show hidden folders on Mac

Open Finder and use the keyboard shortcut Command + Shift + Period (the period key). Hidden files and folders will when ready become visible. Press the same combination again to hide them.

If you prefer a menu option instead, open Finder, click View in the menu bar at the top of your screen, then look for an option that says "Show Hidden Files" or similar (the exact wording varies by macOS version). Click it to toggle hidden files on and off.

Like Windows, this setting persists — once you show hidden files, they remain visible in Finder until you hide them again using the same method.

How to show hidden folders on Linux

The method depends on which file manager you're using. In GNOME Files (the default on many Linux distributions), open the file manager and press Ctrl + H. Hidden files and folders will appear when ready.

In Dolphin (used on KDE Plasma), click the View menu and check the box next to "Show Hidden Files". In Thunar (used on Xfce), go to View and select "Show Hidden Files".

If you're using a different file manager, the keyboard shortcut Ctrl + H works in most of them. If that doesn't work, check the View menu for a "Show Hidden Files" option.

What hidden folders actually contain

Hidden folders typically store process settings, cache files, and system configuration. On Windows, the AppData folder (usually at C:\Users\[YourUsername]\AppData) contains settings for installed programs. The ProgramData folder holds system-wide process data. On Mac, folders like .config and .ssh store process preferences and security keys.

You can look inside these folders to understand how your computer is organized, but avoid moving or deleting files unless you know exactly what they do. If a program stops working after you've deleted something from a hidden folder, you may need to reinstall that program to restore the missing files.

When you might need to see hidden folders

You may need to view hidden folders when troubleshooting software problems — some support articles ask you to check or modify files in hidden directories. You might also need them when moving configuration files between computers, backing up process settings, or accessing SSH keys for remote server access.

Organizing your own files rarely requires hidden folders. If you're setting up a filing system as described in the main article, you'll work almost entirely in your Documents, Downloads, Desktop, and custom folders you create yourself. Hidden folders are there for the system and applications, not for your personal files.

Hiding folders again

To hide hidden folders again, follow the same steps you used to show them. On Windows, uncheck "Hidden items" in the View tab. On Mac, press Command + Shift + Period again. On Linux, press Ctrl + H or uncheck the option in your file manager's View menu.

Your files don't disappear — they're just hidden from view again. This doesn't delete anything or change any settings. It straightforward returns your file manager to its default state.

Frequently Asked Questions

Is it dangerous to show hidden folders?

No. Showing hidden folders only changes what you see on your screen. It doesn't modify any files or change how your computer works. You can safely look inside hidden folders without risk, as long as you don't delete or move files without knowing what they do.

Can I hide specific folders instead of all hidden folders at once?

Not through the built-in settings — the show/hide toggle applies to all hidden files and folders at once. However, you can manually mark individual folders as hidden by right-clicking them and selecting "Properties" (Windows) or "Get Info" (Mac), then checking the "Hidden" box. This lets you hide your own folders separately from system hidden folders.

What if I accidentally delete something from a hidden folder?

Check your Recycle Bin (Windows) or Trash (Mac) first — the file may still be there. If you deleted a system file, the affected program may stop working correctly. Reinstalling that program usually restores the missing files. If you deleted an process settings file, the program will often recreate it with default settings the next time it runs.

Do hidden folders take up less storage space?

No. Hidden folders use the same amount of storage as visible ones. Hiding them is purely a display setting that keeps them out of your way on screen.
