+The object is optimized towards binary reads.
+The object has no multithreading locks, don't use from multiple threads!
+Usage:
+1, Construct a cFile instance (no-param constructor)
+2, Open a file using Open(), check return value for success
+3, Read / write
+4, Destroy the instance

+-- OR --
+
+1, Construct a cFile instance opening the file (filename-param constructor)
+2, Check if the file was opened using IsOpen()
