Opening REG files
Did your computer fail to open a REG file? We explain what REG files are and recommend software that we know can open or convert your REG files.
What is a REG file?
The .reg file extension is used for the Windows System Registry data file format, which was developed by Microsoft Corporation. This is a text-based file format, which is encoded in Unicode for Windows NT 5.0 and later versions. On the other hand, REG files for the Windows System Registry of Windows NT 4.0 and Windows 9X platform versions are encoded in ANSI.
These REG files contain lines of code, registry strings and keys that are used by the Windows System Registry for various OS components, device profiles and installed applications. Some REG files are used by third party application developers for entering data into the Windows System Registry upon the installation or activation of their software products in the Windows computer.
These .reg files can be opened and edited using standard text editors like Notepad. The Windows Registry Editor, which can be launched by typing regedit in the Run dialogue box or in the command line of Windows, can also be used to open and edit the content of these REG files.
