Adding services is simple -- just click the service you want to add and follow the prompts. Each service is listed on the left; click to browse through each. You can rename, delete, copy, move and share files and folders by right-clicking on the file or folder. One comment: It would be better if there were some on-screen icons for those functions.
Viewing files is straightforward -- MultCloud uses Google's document viewer no matter which service you use.
I found the process of transferring files between services to be not a little confusing. At the top left of the screen there are two icons: one for Cloud Explorer (which is MultCloud's main interface) and another labeled Cloud Transfer. You might assume that in order to transfer files between services, you should highlight the file you want to transfer and then click the Cloud Transfer icon. You'd be wrong.
When I clicked that icon, I was led to a puzzling screen that let me transfer a folder from one service to another, but didn't let me transfer individual files. It also let me schedule when I wanted the folder transferred (the scheduling feature is only available for those who use the paid version).
If I wanted to transfer a file, I had to instead go to Cloud Explorer, right-click the file, select "Copy to" from the drop-down menu that appeared, click the Move button, then click Transfer. Not what you would call intuitive.
Apps and for-pay versions
MultCloud is web-only, and doesn't have mobile apps.
The free version lets you transfer up to 2TB of data across cloud services -- when you reach that limit, you'll have to get the paid version for $7.99 per month, which gives you unlimited transfers. The paid version also lets you schedule file transfers and gives you access to more technical support, among other features.
If you mainly want to view files and don't mind putting up with a sometimes-confusing interface for file transfers, MultCloud will serve you well. But its lack of mobile apps is a drawback.
Otixo is another web-based service that treats your cloud services like part of one large hard drive. You set up your cloud accounts to work with Otixo by clicking the appropriate icons and following prompts. It works with 35 cloud storage services, including popular ones like Google Drive, OneDrive and Dropbox as well as lesser-known ones such as FilesAnywhere and MagentaCloud.
When you're done connecting your accounts, each shows up on the left side of the screen. You can browse through the files and folders of each service and perform the usual folder- and file-management tasks, including copying, renaming and deleting. You can also copy and move files between cloud services. And you can easily share files and folders with other people. (More on that later.)
