In Linux, file types are not recognized by file extensions. It is actually determined by the data in a file. The file extension doesn't even matter.

If you run file command on any file, three sets of tests, performed in this order: filesystem tests, magic number tests and language tests to determine the file type.

Go over the file command manual for more information:
Code:
man file
