When using iDisk sync... Do you have to go to me.com and upload your files there? And then your iDisk on your computer syncs with me.com... Or can you simply drop your documents into the iDisk partition on your computer and me.com uploads them for you? I tried the latter method and it said "syncing", but visiting me.com I never see the filed I added to the partition.
No the iDisk is part of me. On me.com you can select how much is set aside for email and how much for iDisk folder. I have 3GB for email and 17GB set aside for iDisk. In the system preferences on the Mac you sign into your MobileMe about and it will set up a virtual folder on your desktop for your iDisk. The data in that folder is then duplicated onto the iDisk in the "cloud". That way when you are not connected to WiFi you can still access the files in your iDisk.
