Bought a myCloud 3Tb yesterday and plan on replacing a part of my Dropbox usage with it.

However, I’m wondering if there is a way to have a client on PC/Mac that offers Offline access.  Like the iOS app where I could mark folders/files that would be sync locally for offline access.

If there is, then I have not found it myself, so I don’t think so.
