List Of Portable Software

Portable software is a class of software that is suitable for use on portable drives such as a USB (thumb) drive or digital audio player or PDA with "drive mode", although any external hard drive can be used. The concept of carrying one's favored applications, utilities, and files on a portable drive for use on any computer is one which has evolved considerably in recent years.

Programs in this category (also known as portable applications) are typically 'lite' versions of their parent software, but there are many exceptions.

To be considered portable, for purpose of this list, a computer program must:

1. Not require any kind of formal installation onto a computer's permanent storage device to be executed, and can be stored on a removable storage device such as USB flash drive, enabling it to be used on multiple computers.
2. Settings are stored with, and can be carried around with, the software (i.e., they are written to the USB drive). If the registry is used to store settings, the application's configuration isn't portable, and must be set up on every PC it is used on
3. Leaves a zero (or near-zero) "footprint" on any PC it is run on after being used. i.e., All temporary files/registry settings should be removed once the program has exited, and files created by the user can be saved directly to the same removable media as the application is stored on.

Generally, smaller utility/toolkit software is inherently fairly portable; though larger applications are sometimes changed in order to allow a portable versions to be released (e.g., Opera@USB and OperaTor).

This is an incomplete list, which may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries.
