winPenPack collects many portable Open Source apps and other free programs.However, I don't like the launcher much so I use PStart as a launcher and PortableFileAssociatoradd file associations to a specific filetype, all files, all folders, the recycle bin, or to all drives. is a well organized package but it only takes the open-source programs.My Favorite Freeware (updated on 03-11-2013)
