Portable version creates files wherever I open a mindmap

Problem:

I have a xmind file located on my desktop
The file name is abc.xmind
Xmind program files are located in C:\PApps\XMind
If I double click on the xmind file on my desktop, within the same folder that the file is located the following folders will be generated: configuration, workspace, p2
Also the file artifacts.xml is created
Within that named folders are 37 files with in sum ~1 MB and 51 (!) sub folders.
If I delete that files, they are created again if I perform step #4 again
If I move/copy (doesn´t matter) the file or create a new one (doesn´t matter), to an other location, then the mentioned files and folders are created there
If I move that created files to the xmind program folder (overwrite existing files), xmind crashes during startup

Please help me using that portable version of xmind.

Ciao
