This button does the same but with 7z archives:
FilesToSeparate7zArchives.dcf (992 Bytes)
(For how to add the .dcf file to your toolbar: How to add buttons from this forum to your toolbars.)
JScript script code for reference:
function OnClick(clickData)
{
var cmd = clickData.func.command;
cmd.deselect = false; // Prevent automatic deselection
cmd.ClearFiles();
for (var eSel = new Enumerator(clickData.func.sourcetab.selected); !eSel.atEnd(); eSel.moveNext())
{
cmd.RunCommand("Copy \"" + eSel.item().realpath + "\" HERE ARCHIVE=.7z CREATEFOLDER=\"" + eSel.item().name_stem + ".7z\"");
}
}
