Seafile 通过“资料库”来分类管理文件，每个资料库可单独同步，用户可加密资料
库， 且密码不会保存在服务器端，所以即使是服务器管理员也无权访问你的文件。
Seafile 允许用户创建“群组”，在群组内共享和同步文件，方便了团队协同工作。
Seafile is an open source file cloud storage platform for file centralized storage, synchronization, and multi platform access.
Question, pay attention to safety and performance.
Seafile classifies management files through a "database", each database can be synchronized individually, and users can encrypt data
The library, and the password will not be saved on the server side, so even the server administrator does not have the right to access your files.
