Cloud storage is proving to be more than just a place where you can store volumes of data and files.

Today, you can move around with your office virtually, no matter the location, and access any of your files and/or data from your computer or device.

What’s more, it can be used by individuals, or small and large organisations alike, saving you time, stress, and costs that come with finding storage devices (which you also have to keep carrying around) and this can be cumbersome.

However, there are free cloud software for Windows that you can use, which offer a wide variety of features from storage, to syncing data, work team collaboration, and so much more.
