Portable software is a class of software that is suitable for use on portable drives such as a USB drive, not require any installation, save settings into own folder and can be moved easy. Software present on WinPenPack, and also the single packed programs, are always standalone, so they don't need setup procedures. In fact all portable apps can be directly launched from your pen drive, passing through a simple and useful main menu, very similar to windows quick launch. This launcher, called winPenPack launcher, was written and is supported by winPenPack Team. When your pen drive is plugged into the host PC, you can immediately have your preferred apps ready to go.
