All cloud services though one app

[deltaforce]

I just came across Primadesk and Otixo. The concept is good but either they are webapp or paid or there is something I don't like about them.

I wonder if there is one app, which takes storage from many cloud storage places and acts as one cloud space, so that whatever storage you have in the cloud can be accessed through one app, instead of checking each folder to see where it is.

Thanks in advance.
