UploadGround: Uploads files to multiple network disks at the same time

UploadGround allows users to upload files to multiple network disks at the same time. In this way, users can back up the same document to multiple network hard disks, reducing the trouble caused by the loss of documents, and also solve the problem that some network hard disk services can not be used in the country, but also choose to use the fastest download storage space when you need to download.
