How to move portableapp

If you use the PortableApps platform (Menu etc.),it's easiest to start a fresh install on the destination drive and then just copy the whole contents of the PortableApps folder of the source drive to the PortableApps folder of destination drive. Every portable app from here is designed to deal with the drive letter and folder changinging.
If you don't use the platform, skip the installation process.

You can copy an individual app's folder (FirefoxPortable, etc) or you can copy your whole platform (Documents and PortableApps folders along with Start.exe) from one location to another and it will continue to work.

The dirty little secret about windows is that the more programs you install, the slower it runs. When you install a program, it writes data to the windows registry. The windows registry is a database. The more data you write to the database, the longer it takes to do database lookups. That slows down everything. When you uninstall a program, it usually leaves some data behind in the database. Eventually, you have to reinstall windows and reinstall your programs to get the speed back. Okay, maybe that's not a secret, but here is a workaround.

Portable apps are designed to be installed to a USB flash drive, that you can move from machine to machine. The installation program simply copies the program, and its associated files, to a folder on the drive without making any changes to the windows registry. If you want to uninstall the program, you simply delete the folder on the drive.

But you don't have to install portable apps to a USB flash drive. You can install them to your hard drive and use them like any other program. But the one caveat is that because they don't write to the windows registry, they don't integrate with windows. If ,for example, you were to install the regular version of VLC player, it will write to the windows registry and associate itself with video files so that you can play a video file in VLC by simply double clicking on the video file. If you install the portable version of VLC, you don't get that feature (although you can still manually set the file associations to do this).

So here is how to install portable apps to the hard drive. First, download the Portable Apps Platform. This gives you a nice little portable apps start menu and an easy way to manage updates. When you install the platform, choose New Install.
