I have an Interop class that works properly. However, I don't know wich
COM-object it calls (I'm not the one that created the Interop class).

How can I find out? I've tried to look at the code generated by ildasm.exe
and remotesoft salamander, but I can't find the call to the COM-object. All
I can find is the method signature for the Interop method, wich casts the
string arguments using ([MarshalAs(UnmanagedType.BStr)]

take a look at which interfaces the interop assembly defines
and dump the GUID-attribute:

Debug.WriteLine(typeof(ISomeInterface).GUID);

or inspect the GUID-property of an object of those interfaces:

Debug.WriteLine(someObject.GetType().GUID);

Doesn't that only return the GUID of the interop class? Or does it actually
return the GUID of the COM class? If so, how do I find out the file name
(dll-file) that this COM class is located in?

No, it's the "real" COM GUID. The DLL you look up from
the registry. The path is HKEY_CLASSES_ROOT\CLSID\.
