The NetEase Cloud Disk attached to the NetEase email (not the "Yi Pan" 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 up to 50M), folder compression downloads, adding descriptions for files (folders), and online previewing of image files (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; only one can be activated per phone number) just need to activate the mobile mail service for free to obtain (or upgrade to) 512M of NetEase Cloud Disk space (see Figures 2, 3), and the total size of email attachments increases to 2G (single file 1G). This event is not permanently valid, so those who need it should act now O(∩_∩)O~
