MultCloud

With MultCloud, you can easily sync two cloud services or two folders on different cloud accounts. You can also set up scheduled sync to sync your data between clouds at a certain interval automatically. Connect all your clouds to MultCloud and you'll find it so easy to access and manage all your online files with a single login. Upload, download, copy/cut, paste, preview and rename your online files just like in Windows Explorer. And as multiple free cloud drives are integrated, you actually have the way to "expand" your free cloud storage. The process of transfer runs on the server of MultCloud, so the data is still transferring even when your device is power off. As it is offline cloud sync or transfer, once you launch data transmission, you can simply shut down your browser or computer and leave the rest to MultCloud.
