Sandboxie Support

I see what you're saying, since the dev(forget his name, sorry) isn't going to add blocking all folders but X then selecting multiple folders is the only way to achieve such a feature.

Yes of course.

When adding multiple folders to the blocked file access it becomes tedious having to reopen the dialog for every folder you want to add (http://i.imgur.com/yacB1f7.png)
It would be much appreciated if you could enable multiple folder selections at once.
