The PortableApps Suite is a storehouse and management system for "portable" versions of some of the most popular freeware around. That collection used to be limited only to open-source programs. But on Wednesday it started making portable versions of closed-source freeware to users. The first batch of portable freeware includes Web browser Google Chrome, VoIP client Skype, BitTorrent client uTorrent, antispyware tool SpyDLLRemover, and three others at the time of writing. The new portable versions of these programs work both independently and in tandem with the PortableApps suite.

In a statement published on its Web site, PortableApps.com founder and CEO John Haller said that PortableApps "remains committed" to open-source software, but that closed-source freeware publishers would find other venues for USB stick-friendly versions of their programs if PortableApps didn't open its doors to them. For users that want to support only open-source programs, he said that the PortableApps directory will soon be filterable.

PortableApps is also planning to accept portable versions of commercial software, although it hasn't announced a timeline yet. Readers can check on the latest updates to the PortableApps catalog at their Web site, although we do host most of them at Download.com as well.
