File Extension REG

File type: Registry Data File

Notes about the REG file extension:

Errors in your registry are one of the common causes for incorrect file associations on your windows system. It is highly recommended that you check your registry for file association errors (will also check for any other registry errors).

The REG file type is primarily associated with 'Registry Data File' by Microsoft Corporation. Typically used to make repairs to or save data from the Windows registry. Use, with caution, the Windows Registry Editor to create a .REG file. All you have to do is "run" the file (double click on it) in order to insert the values into the registry. Do this with even more caution! Changing the registry improperly can result in your system no longer working. Note: This file type can become infected and should be carefully scanned if someone sends you a file with this extension.
