The NetEase Cloud Disk attached to the NetEase email (not the "Yidisk" introduced earlier) is one that many friends have used. Although it does not support external links, its stability and convenience are quite reliable. Moreover, it now supports batch uploads (single file 50M), folder packaging downloads, adding file (folder) descriptions, online previews of image files, and other new features (see Figure 1). It can be considered a pretty good private cloud disk.
Unfortunately, in the past, this cloud disk required exchanging email points, and the maximum capacity was only 280M (larger capacities required payment). Recently, NetEase has launched a free activation/upgrade campaign for its mobile mail service to promote it. NetEase email users (including 163, 126, yeah, and only one can be activated per phone number) just need to activate the mobile mail for free to get (or upgrade to) 512M of NetEase Cloud Disk space (see Figures 2 and 3), and the total size of email attachments increases to 2G (single file 1G). This activity is not permanently valid, so those who need it should act now O(∩_∩)O~
