What makes a portable app special?A portable app is a big leap forward for apps in general.  A standard or traditionally engineered app requires a lot of support in the form of libraries, data files, images, scripts, etc and the list goes on.  You get the picture.  Some portable apps out there still include this bundle of bits, they merely offload it into a local folder.  A dump of goodies of sorts.

We tend to see a portable app in quite a different light.  Our vision of a portable app is designed tight, clean, free of bloat, and all data where possible is included directly within, structured right into the fabric of the app itself, and designed from the bare-metal up if required.

Though the most important difference between a traditional app and a portable app is that a portable app will not install on your computer.  This is extremely important as the installation process is often messy, and can clutter up your computer by dumping a lot of stuff all over the Windows file structure and registry, and over time may slow down and decrease the overall performance of your computer.

A portable app will not do this, which keeps your computer clean and running smooth and fast as it should.  Unfortunately most software is not designed with portable in mind.  They're more akin to a large leaky box of bits than tight engineering.  And because a portable app is not installed on your computer, it runs outside the normal scope of the operating system, and is not locked down or tied to it.  And thus can be moved about, from disk to disk, or computer to computer.

Typically a portable app will reside on a USB pen stick, removable media, or in a special folder on a portable hard disk.  This makes it easy to take from one computer to the next, and use over and over.  An immensely valuable freedom, and something an installed app can only dream of.

But a serious technical hurdle must be overcome for a truly portable app to be free.  And that is the humble setting.  Yes, a portable app must be able to handle it's settings on it's own.  It must be able to read them from disk, filter them, check and correct them where required, and write them back to disk.  All without the help of the Windows' registry or other operating system dependent structures.

An installed app typically can't or won't do this.  Instead, it relies on Windows and the registry to manage it's settings and other important data sets for it.  It therefore takes a higher degree of technical competence to escape this "tied to the operating system" situation.

Here is our current standard for a portable app:
