Now I tried it again and it works perfectly! I don't know what I did wrong before!
Maybe I used the autosize wrong and the settings were overruled as you mentioned.
Thanks a lot for your help!
As I understood the function/option "Make folder list" will come later. Right?
Right, there was a "todo list" on the FC pages, but it's gone. Features like "Make folder list" and FTP client are planned after releasing the final XE version. Most of the features from old version have been implemented already, the rest will be implemented later. It all depends on author's free time.
