WinSnap Portable Edition is a special edition of WinSnap designed to run it from a removable media (USB flash drive, iPod/MP3 player, network share, etc). Simply extract the content of one of the program archive onto your portable device and you're ready to go.

Usually the standard version of WinSnap also does not require installation instead of creating shortcuts (the setup program additionally checks compatibility and already installed versions, allows to choose directory and components to install). But the standard version uses Windows registry to store their settings... and therefore it is not fully portable! The Portable Edition stores all settings into the same folder as the main executable. This allows you to copy & move your settings with the application folder.

Also, the default Auto-Save folder does not depend on drive letter. It is very useful if you are running it from a USB stick on different computers (from different drive letters, actually). So you can make screenshots and automatically save them in the same location on your portable device.
