RAR archive with password

When I open an archive that has a password, the folder opens and shows no files. But there is no option to enter a password to access the files.

Is there any way to do this in DO? I could download a freeware utility, but what I love about DO is that it does so many things that it saves me from filling my disk and memory with other apps.

I would presume that you need WinRAR to do some of the advance features that rar has like passwords and encryption.

I have WinRAR installed and simply added a WinRAR option to the context menu so that rar files will open in WinRAR.

I was using ICEOWS, which is pretty good. But I can already do ZIP in DO and would love to not have to get another app.
