Long: `copy one or a list of files, or batch copy one whole folder recursively, to a filer folder
It can copy one or a list of files or folders.
If copying a whole folder recursively:
All files under the folder and sub folders will be copied.
Optional parameter "-include" allows you to specify the file name patterns.
If "maxMB" is set to a positive number, files larger than it would be split into chunks.
