A file extension is a suffix to the name of a computer file. The file extension is often separated from the base filename by a dot or space. For instance, txt is the extension of the filename readme.txt and html is the extension of mywebsite.index.html. Commonly, file extension can help Windows identify the file formats.

If a file extension is modified mistakenly, you will not be able to open the file or associated programs. Sometimes, you can also know whether your PC is in a safe condition through files extensions. That is because an error file extension can be caused viruses. If a file extension is not displayed correctly, you can use your antivirus program to check whether your computer is infected with a virus or not. If not, you can use a system repair tool to fix error files in time so that you can avoid unnecessary troubles.
