What is File Extension?

The file suffix, also called the title extension, is what comes at the end of a file. When you open a file, your operating system (like Windows or MAC) needs to know what program it belongs to. That is where the file name comes in.

File names tell you about the type of file you have. For example, a document file ends in.doc, and you’ll need a word processor tool to open it.

It’s easy to understand: file names tell you what kind of file it is. Take a look at these popular file extensions: PNG, MP4, MP3, EXE, LOG, and more.
