How to display file extensions and view file extensions on Windows 11/10/7/8
Why should you display file extensions on Windows?
Each file has an extension called file extension, which allows Windows and users to know what type of file it is. File extensions usually contain three or four characters, but can be longer in some cases. For example, a Word document file has the extension .doc or .docx . If you have a file named Example.docx , Windows will know it's a Word document and will automatically open it with Microsoft Word by default.
There are many different file extensions. Audio files can appear with extensions such as .mp3, .aac, .wma, .flac, .ogg. While some common image file extensions are .jpeg, .png, . gif and .heic.
In addition, setting Windows to display file extensions also plays a very useful role in security issues. For example: The .exe extension is one of many types of file extensions that Windows will run as a program (executable file). If you can't see a file's extension, it's difficult to tell if it's an executable, a document, or a secure media file.
As a simple example, you may come across a file named ' document ' with the icon of a PDF reader installed on the system. If the file extension is hidden, there is no quick way for you to determine whether this is a legitimate PDF document, or just a malicious program masquerading as a PDF reader icon. . If you've set Windows to display file extensions, you'll be able to easily check whether it's a safe document called ' document.pdf ', or a hidden file containing dangerous executable code like ' document.exe '.
Display file extensions on Windows 11
Microsoft changed the File Explorer user interface quite a bit between Windows 10 and 11. But overall, the process of setting file extension display options can still be done relatively easily.
First, you launch File Explorer on your Windows 11 PC. On the File Explorer window that appears, click on the ' View ' tab in the upper left corner of the screen. After that, a drop-down menu will immediately appear, hover over ' Show ' at the bottom of the menu and click on the ' File Name Extensions ' option in the sub-menu that appears.
It's all that simple. The extension will now be displayed for all files, in all folders on your computer.
