If you want to see the file extensions in Windows 10, it’s a simple process. You just need to adjust a few settings in File Explorer. Open File Explorer, go to the View tab, and check the option for file name extensions. That’s it! Now you can easily see what kind of files you’re dealing with.
How to Show File Extensions in Windows 10
To show file extensions in Windows 10, you’ll need to navigate through a few settings within File Explorer. This will allow you to view the full names of your files, including their extensions, making file management easier and more transparent.
Step 1: Open File Explorer
Launch File Explorer by clicking on the folder icon in your taskbar or pressing the Windows key + E.
File Explorer is your central hub for accessing all files and folders on your computer. Getting familiar with its interface allows you to perform many basic and advanced tasks efficiently.
Step 2: Go to the View Tab
Once File Explorer is open, click on the “View” tab located at the top of the window.
The View tab contains various options that let you customize how you see your files and folders. By exploring these options, you can tailor the appearance of File Explorer to fit your preferences.
Step 3: Check File Name Extensions
In the View tab, find and check the box labeled “File name extensions.”
Checking this option will display file extensions for all files, so you’ll be able to see if a document is a .docx, a .pdf, or something else. This helps in identifying file types at a glance.
Step 4: Review Your Files
Look at the files within any folder to confirm that the extensions are now visible next to file names.
This visibility ensures you won’t accidentally open or send the wrong file type. It’s an easy way to prevent confusion, especially when dealing with multiple files of the same name but different formats.
Step 5: Close File Explorer
Once you’re satisfied, you can close File Explorer by clicking the X at the top right corner.
Closing File Explorer will not affect the changes you’ve made. The settings will remain in place for future sessions unless you decide to change them again.
After completing these steps, every file you view in File Explorer should have its extension visible. This change benefits anyone who frequently manages files, making it simpler to identify and organize different file types.
