I'm trying to create a custom context-menu entry for Windows (7) Explorer that will send ALL selected items ton ONE single command.

I've read about MultiSelectModel with a Player value in MSDN Doc but this does not seem to work. That's what I've tried:

  1. under HKEY_CLASSES_ROOT/*/shell created a key "MYVERB"
    1. (Default) for 'myverb' is 'my verb'
  2. under "MYVERB" created a key "COMMAND"
    1. (Default) for 'command' is 'python C:\ "%1" "%2" "%3" "%4" "%5"'

This works fine for one item.

But when many items are selected, the script is launched one time for each of them. Instead, I want one only instance to receive all the selected items.

I tried adding a String Value "MultiSelectModel" -> "Player" both under "MYVERB" and "COMMAND" but the behaviour does not change.

Is what I'm trying to do even possible with a script and registry only? What am I doing wrong?

This is currently unsolved, even though I accepted Tom's answers to grant the bounty in appreciation of his efforts – Stefano Jan 4 '12 at 16:02

Here is an example:


You don't have to specify any % parameters when you use Player, only the command itself.

You might want to try to use a script that prints the command line to a file so that you know what's happening under the hood. But I think that in this case the specification of "%1" and so on broke it...

Thanks Tom. I tried removing the parameters but still having the same problem: one command per file is launched. My command is now simply "C:\test.bat". Any other idea? – Stefano Dec 17 '11 at 11:25
You might have to test to see if you are already running/just have run. There might not be a way around this. – soandos Dec 22 '11 at 7:50
@Stefano: The MSDN document doesn't really mention how exactly it works, as soandos mentions it is quite possible that it just calls an application one argument at a time and that you will have to gather them and delay execution till after they are received. Do something like "if I don't get another item for 1 second, I have received everything". If you really need them all... – Tom Wijsman Dec 22 '11 at 12:21
Thanks Tom, you are probably right, in any case you are the only one who tried to help! – Stefano Dec 22 '11 at 15:20
Why did you accept this answer if it's incorrect? – zenpoy Jul 17 '12 at 11:39
