Cloud - Multicloud collector

I adding this applicative mention:

I did not find time to test it but it seems useful.

It is Web based app that allows multiple cloud users to access all their online files from a single interface. Organizing, transferring, synchronizing or even manage sharing files between cloud storage services like Dropbox, Google Drive, Copy, OneDrive, FTP, WebDav, MEGA and other cloud supported vendors.

It is a free application.

There is a premium plan too:

About security concerns consider that:

  1.  Website connect and data transfer using 256-bit AES encryption for SSL.
  2.  Does not save or cache your data and files on our servers.
  3.  Access cloud drives with OAuth authorization and does not save your password.
