How to Show File Extensions in Windows 10: File Extension is ending of a file which helps in identification of the type of file in Windows 10. For example, the file name “example.pdf” has the file extension “.pdf” which means the file is associated with adobe acrobat reader and is a pdf file. Now if you are a novice Windows users then it’s very important to see file extension in order to identify the type of file you’re trying to open.
But first, you should know why file extensions are important, well, it’s important because you could click on malware/virus files without even knowing so. For example, you downloaded a file security.pdf.exe, now if you have file extension hidden you will only see the file as security.pdf which is a big security risk as you will definitely open the file thinking it of as your pdf file. This file could potentially damage your system and that is why file extensions are important.
When file extensions are disabled you would still see the icon of the program which is associated with that file type. For example, if you have a file test.docx, then even if you have file extension disable, you would still see the Microsoft Word or the default program icon on the file but the extension “.docx” would be hidden.
This doesn’t mean that you can’t be tricked by virus or malware because they can disguise the icon of your file type and still be a malicious program or application, so it always a good idea to enable file extensions in Windows.
