k550 Newbie help please

in that xs++ tutorial step 5, it is mentioned that some features like these will not be allowed after modifying the phone...is it so???

Some Important Things You Need To Know Before Using FSX:
A: You cannot 'download' files from your phone.
B: Smartphones are not supported by the FSX function.
C: You cannot mark multiple files.
D: You cannot delete folders.
E: I've included a list of most used files in the end of this FSX section.
F: Files are overwritten if you upload a file with the same name..
(You don't have to delete all the acoustic file before uploading new ones)
