Copy file with lib connection name

[amals]

I want to copy series of files from working directory to achieve directory once processing is done. Files are in working directory refer by Lib Connection name xxxx. So for file copy I used to execute external cmd command using Execute command. All necessary setup for run Execute command has been done. Here below command proceed without error but no files get copy.

Is it possible to refer source file and destination with lib connection name in Qlik Sense?. If not how could I get physical file path from lib connection and refer them on copy command.?   

EXECUTE cmd.exe /C copy [lib://xxxx/yyyy/1.qvd] [lib://xxxx/archieve];

We have an option to execute as external program in QMC tasks, In case needed.

The Execute with .EXE won't work if your tool is not a legacy mode.
