Development platform
> Based on QT5.8.0 MINGW version, the development and running environment is win 64bit
Basic functions
1. Tools include server and client;
2. It has the functions of user registration, login, and password retrieval (based on TCP protocol); 3.

File transfer has good performance and can make full use of network bandwidth;
expected functionality
The server side is completed on the Linux machine and deployed to the cloud host.
The server process is made into a service process of the host
The database stores user information and supports user registration to retrieve passwords. It is expected to support password retrieval via email.
File transfer is changed to TCP, using multi-threaded transmission
