What Are File Extensions?
File extensions are file types like audio files, video files, word files, and excel files. The audio file will only run on compatible audio software, as a video file will only run with video-compatible software.
File extensions are hidden on Windows computers by default. By seeing the file extension, you can easily tell which type of file it is. All file types will have different file extensions like .wav, .mp3, .wma, .docs, .XML, etc.
The operating system opens any file by understanding its extension and then decides which program can operate/open this file.
File name allows us to use multiple full stops, and malware also uses the same extension type as rock.docx.exe. At the same time, you will find this type of file in windows as rock.docx because, by default, Windows does not show extensions.
