File extensions help identify a file’s type and the app that can open it. On Apple devices, you have the option to show or hide file extensions depending on your workflow preference. Whether you’re on a Mac, iPhone, or iPad, the process is simple and helps manage file visibility across devices.
Why Show or Hide File Extensions?
- Show extensions to quickly identify file types (.pdf, .jpg, .docx)
- Hide extensions for a cleaner, minimalist look
- Developers or power users often prefer extensions visible
- Great for managing shared folders and downloads
On Mac: Show or Hide File Extensions for One File
- Right-click or select the file.
- Click File > Get Info from the menu bar.
- Expand the Name & Extension section.
- Check or uncheck the box labeled Hide extension.
This lets you manage file visibility per file, useful when only certain files need clarity.
On Mac: Show or Hide Extensions for All Files
To apply changes system-wide:
- Open Finder.
- From the top menu bar, click Finder > Settings (or Preferences on older macOS).
- Go to the Advanced tab.
- Check or uncheck Show all filename extensions.
Your Mac will now display or hide all extensions, depending on the setting.
On iPhone and iPad: Show File Extensions in the Files App
Since iOS 16 and iPadOS 16, you can enable this natively:
- Open the Files app and navigate to a folder.
- On iPhone: Tap the three dots in the top-right corner.
On iPad: Tap the four-square icon in the top bar. - Select View Options.
- Tap Show All Extensions.
📌 To hide extensions again, just revisit the View Options and deselect the same setting.
Limitations to Note
- iOS only applies extension visibility per folder, not globally.
- Some Apple native apps still hide file extensions regardless of setting.
- Extensions remain visible in shared folders when enabled, which may affect file presentation.
Conclusion
Whether you’re a developer, student, or casual user, knowing how to show or hide file extensions on your Mac, iPhone, and iPad empowers you to manage your files with more precision. Make your workspace as clean or as informative as you need.
