Question

Yandex.Disk

Today I received a letter that the pretty good service otixo.com is becoming paid, and therefore I am looking for a free analogue of such a service. Who does not know what kind of service I will explain: otixo is a service that links Dropbox, GDrive, Picasa, YDisk etc accounts .

Answer 1

Look at these:
Primadesk
ZeroPC

Answer 2

How does this service link <list of accounts>? i.e. what do you need from the service?
