Rosetta provides a rich set features to manipulate various media types and applications. Rosetta xtra will not be complete without a set a functions to manipulate the file system for which all applications and media files resides on. Rather than asking Rosetta's users to use a separate xtra for simple file system tasks, everything is now built in.
Some of the functions in the file systems may do more than the function description says. For example, Rosetta have the function sysFileMove; judging from the function name, it can be assumed that this function is used to move a file from 1 location to another. Implicitly, this function can be used to rename files too.
