With portable applications, those that require no installation on a Windows based PC, you can truly carry powerful software in your pocket. There are enough types of software to cover most any personal or business need. Being able to use business software, utilities and even games from a USB Flash Drive is very handy.
Three of the major collections of portable applications are:
Portable Apps - www.portableapps.com (download apps menu then select software from there to install. All the software installs under a folder called PortableApps)
Pendriveapps - www.pendriveapps.com (download apps to any folder you choose)
Liberkey - www.liberkey.com (Prepacked set of applications from 4mb to 300mb of downloads)
I have used the launcher from PortableApps for quite a while and it allows you to select apps from different categories after which it downloads them to wherever your PortableApps folder resides. The launcher can also be set to automatically notify you of software updates. Click below to find out just what kind of applications are available.
