The PortableApps Suite is a collection of programs specially packaged for use from your USB thumb drive, or other portable drive. That means wherever there's a Windows computer you can use "your" apps without installation or changing the host machine's preferences.
All the apps included are open source, and include the Firefox browser, Mozilla Thunderbird email client, the OpenOffice.org suite plus anti-virus, instant messaging, audio players and more. After installing the package on your portable drive, the suite can be used on any Windows computer simply by plugging in and double clicking as usual.
While you can download all of these apps in portable form separately, one advantage of the PortableApps Suite is its integrated menu. Once opened, this sits in the System Tray, and pops up when clicked. Here you have all your portable apps ready to go, plus documents, music pictures and video folders. From the menu you can also add other portable apps of your choice, update them, and keep an eye on your drive with the capacity bar. It really is like carrying a little computer around without the machine!
The downside of this for some people will be the programs included. They are all open source, and while we think OpenOffice, for example, is a great alternative to Microsoft Office, it may not be to your taste. The current download also inexplicably includes the old version of OpenOffice.org, although this can be quickly remedied in the PortableApps menu.
This is a great way to take your apps and documents with you without dragging your computer along with you.
