+##Product description
+Several functions for file management are demonstrated here, such as creating files and directories, 
+renaming, deleting and copying them as well as reading and writing files. 
+A directory can be browsed to find all included files.
+
+In the synchronous way, the function will wait until a result is returned. Sometimes this lasts longer 
+than one cycle. There for an asynchronous call can be used. Here the function will not wait for a result. 
+At each call the function will ask again for a result, when it is available the variable ``xDone`` is set 
+to true, otherwise it stays false until a result is available.
+
+
+##More information
+``SystemDir``: Several synchronous functions are used to create a directory. 
+The directory is browsed to find all included files. After renaming, the directory will be deleted.
+
+``SystemFile``: Several synchronous functions for file modification are used. 
+First the file is opened with write access. A string is written to the file and it will be closed after. 
+The next step opens the file again and reads the written string. After copying the file a new string is 
+appended at the end. Some file information like creation time and size are retrieved as well.
+
+``CAA_Dir``: It shows how to create, open, close rename, browse and remove a directory. This is done in an 
+asynchronous way with use of a state machine. When the function block is done or sends an error, 
+the ``Next`` or ``Error`` state is reached.
+
+``CAA_File``: This program does some file modification in an asynchronous way. After opening the file 
+a string is written into that file and later read again. File information are fetched as well as appending 
+another string into the file.
