Detailed Description

Provides access to (part of) the local/remote file system.

Part of refers to the fact that read and write access may be limited by specifying (a number of) roots via the "data" path. The "data" path is a ';' seperated list of directories in the real file system to ease/shorten file naming. Writing is only allowed in the first root. For reading, all root are inspected in order. The dataServer argument indicates whether the file system is remote.
