What is the meaning of a file extension?

File extensions are characters that appear after the dot in a computer file's name. For example, the file "unknown-file.oxm" has the file extension "oxm". This is used to identify which program should open the file or what file type it is.
File extensions help you organize and manage files. They provide a quick and easy way to identify and associate the file type with the appropriate software.
