windows下的多线程拷贝工具, 对标rsync

robocopy

Reference article for the robocopy command, which copies file data from one location to another.

https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/robocopy

常用:

参数:

/e Copies subdirectories. This option automatically includes empty directories.

/z Copies files in restartable mode. In restartable mode, should a file copy be interrupted, Robocopy can pick up where it left off rather than re-copying the entire file.

/MT[:n] Creates multi-threaded copies with n threads. n must be an integer between 1 and 128. The default value for n is 8. For better performance, redirect your output using /log option.

Caution: 如果src_path只是文件夹, 则robocopy只会复制该文件夹中的内容到dst_path, 而不为将这个文件夹复制到dst_path (即使添加了\)

因此需要在dst_path后手动追加对应的文件夹名称, Eg:

src_path: G:\mymusic | dst_path: H:\data
