This dongdong is to do to the company data synchronization: The new server has not been officially enabled, the old server is still in use, a large number of pictures uploaded to the old server every day, in order to avoid back up all the pictures, so write a tool.

1. The operation effect is shown in the following illustration:

2. The Python code is as follows:

Copy Code code as follows:

Recursively lists the files in a directory and puts them in the list.

3. Configuration file name: Config.ini as follows:
Copy Code code as follows:
