Offline folder

Can I use my cloud in a fashion similar to drobpox i.e. there is a folder on my computer that is synced with my cloud and the folder contect is available when my computer is offline?

Aside from the autobackup software on the MyCloud, there are a few other ways to have a system which has a service identical to Dropbox.   You can install ownCloud or Barracuda Drive softare on the MyCloud.

Without loosing warranty?
