Answer by ThorD125 for Open With on multiple files?

I think this registry script will do a better job.

Explanation:It calls for a program.exe but this does not exist and therefore it opens the shell to chose an application.Because of this you can even do it with more files and even with different file extensions.

Disclaimer: This does not open only ones it actually opens for every file another application choser.

To install: paste the script in a txt file and save as filename.reg and dubble click the file.

Windows Registry Editor Version 5.00[HKEY_CLASSES_ROOT\*\shell\Open With\command]@="program.exe"
