Is there a real alternative to SugarSync?

Question

Android

What I need from the cloud:
1. To synchronize any folder both on the desktop and on mobile devices (smartphone, tablet - Android). Because of this, Cubby disappears - on android, he shoves files so far that it's even scary. There is a standard Books folder - I want all my books to be there. And they all have to be in the cloud. By the way, SugarSync didn't know how to do this either, as far as I know, but at least it had an intelligible folder - SugarSync folders.
2. At least 5 GB for free. I don't need more yet.
3. Convenient file/folder management - every cloud storage should be able to do this by default

Answer 1

bittorrentsync. Not suitable for point 2, but everything else is perfect. There is no "cloud" server at all. Only point-to-point between your machines. But as much space as you want.

Answer 2

Yandex.Disk or SkyDrive

Answer 3

There is Wuala.com. It fits the description, though I don’t know what is in the mobile version.
