RegCOPA Registry Editor - The Registry

What follows is a very brief overview of the Registry and its functions.

More details can be found (at the time of writing, October 2007) at:

An internet search will also reveal many other useful resources.

In the 'good old days', hardware and software installed on a machine would mostly have its own Initialisation Files (eg config.ini), text-format files containing various information relating to its owner, configuration etc. Unfortunately, these became scattered across the directory structure, each with its own schema. There were also limits on the size of these files.

These factors, together with a massive increase in the amount of information needing to be stored and accessed quickly led to the development of the registry as a centralised, standardised repository of information related to the computer's hardware and software.

Keys can be exported to a .REG file, and later imported into the registry on the same computer, or on another.

RegCOPA allows the opening, editing and re-saving of these registry files, but NOTE that there are two formats which are quite different:

Version 4 for Windows 95, 98, ME and NT
Version 5 for Windows 2000 onwards (XP, Server 2003, Vista)
