Hi, Thanks for the detailed clarifications
I tried using your suggestion to create a multi-7z archive...
@set name={dlgstringS|Name|{file$|noext}}
CreateFolder {$name}
Copy HERE ARCHIVE=.7z CREATEFOLDER={$name}
Split {$name}.7z SIZE 1MB TO "{sourcepath}{$name)"
...except the split parts do not get put into the named subfolder as I wanted.
P.S I'm inclined to use winrar exclusively, only because I would like to have a pre-configured password and automatic encrypted multi-archive creation. Having found
[url]WinRAR Compress/Decompress Buttons (and other)]
Still deciding though
