How to transfer more than 1 file to an application through the Windows right-click menu?

Question

Windows

I add the menu item with a reg file:

[HKEY_CLASSES_ROOT\*\shell\S2FFREC]
@="Конвертировать"
"Icon"="imageres.dll,162"
"Position"="top"
[HKEY_CLASSES_ROOT\*\shell\S2FFREC\command]
@="wscript.exe \"\\\\192.168.0.100\\scripts$\\convert.vbs\" \"%1\""

In the explorer, I select several files and click this menu item - the files are transferred to the script one by one.
How to transfer all files at once?
Let me explain why: it will be necessary to "glue" several clips into one, and at the same time several gluings should be performed in parallel.
My knowledge in Delphi is enough to somehow write an analogue of the conductor, but many options are already hanging on the right button - everyone is used to it, I would like to implement everything one menu...
