Why combine your cloud storage?

There are so many different cloud storage services available today such as Google Drive, OneDrive, Dropbox, etc. With them, you can store files without consuming the storage space of the local computer. And with more and more people using cloud storage services, the demand for combining cloud storage also increased for the reasons below:

To expand storage space: Generally, all of these clouds provide multiple gigabytes of storage space for free, but free storage space can be quickly exhausted and you need to pay extra to get more storage. In this case, you may want to combine several clouds into one for large storage space.

To improve performance: All of these cloud services offer their own client software and have to be accessed through these different clients. If you do not want to have dozens of cloud storage clients running in the background on your PC, you would want to combine your cloud storage.

To save the effort: Tired of logging in to each account every time and managing files among several different cloud drives, you would want to combine multiple cloud storage accounts. And with combined cloud drives, you can easily transfer files or folders from one cloud drive to another without the need to download them to your computer and upload it to the cloud, saving much effort.
