Great idea, still rough

First, you need a Synology network disk. Then you need to log into it and install the DS Cloud app in the disk, then set it up - tell it what folders to share. Then you can install this app on you iPad or iPhone (or both), and youre good to go.
For me the problem was that the DS Cloud app on the disk began to grow until it used up 100% of a 1Terabyte drive, making the disk unusable, for sharing a few megs of files. I just uninstalled it on the Synology disk and the space gradually came back. Maybe I did something wrong, but I have no idea what. When Synology either fixes this bug, or documents how youre supposed to do it, this would be a great system.
Note that it also keeps past versions of your files - maybe that was the problem? - so you can roll back to look at older versions.
