Sorry for my idiot reply, but I still don't understand. So again, I connect N900 to computer by the USB. On N900 I click on PC Suite mode or Mass storage mode? I click on PC Suite mode, then in computer I have "apliccation" N900 (PC-Suite Mode) - you said "open it" what I have to open? N900 (PC-Suite Mode) and then paste a file there? It's not go, I can only save a file to (Audio Clips, Data, Documents, etc)

I maybe don't understand to sentence "MyDocs is the root directory of your N900 under your PC." English isn't my language, I am from Czech, so..sorry
