The progress of my logged test was as follows: Opening _66P\Fonic\fonic-Anfrage.txt, and closing it. Opening the directory _66P\AMDchipset8WinXP-PC6 and closing it. Opening _66O\ATI_RadeonX800_Linux64\installieren.txt, and closing it. Opening _66O\B2100 - the error occured, the directory seemed to be empty. Closing the subdirectory "B2100". Clicking "F5", the contents of the directory changes. Trying to open the subdirectory "ASound" shows an empty window, because this directory is really on _66P, not on _66O.
