Linux file extension and type

Windows is a file type that is distinguished by extension

There is no relationship between the file extension root file types in Linux

In order to easily differentiate and be compatible with the user's habit of using Windows, we also use extensions to represent the types of files in Linux!

Everything in Linux is file. File types include: normal files, directories, character devices, block devices, symbolic links, etc.
