[VFS] What does GET_TYPE entail?

[Schalk Cronjé]

The description for Capabilities.GET_TYPE states that "The file type can 
be determined". Does this mean it can be determined in

   - A way similar to Unix 'file' command?
   OR

   - A way similar to MIME Content-type?

Secondly can someone point me to where is actually been used in the core 
code to make a decision? I cannot find anything in core.
