What is a .CLG file?

The file extension .CLG stands for a Collage Maker Project File, but it is more commonly known as a catalog file used by a program called Windows System Image Manager, which is part of Microsoft Windows. The .CLG file contains detailed information about the contents of a .WIM file, which is a Windows Imaging Format file. This includes details about the state of all packages and components within the image.

The main purpose of a .CLG file is to help users view what is inside a .WIM file without having to open the entire file, which can be very large, often several gigabytes. In contrast, .CLG files are usually quite small, typically less than one megabyte.

You can find .CLG files on Windows installation discs. For example, on a Windows 7 installation disc, you might see files like HOMEBASIC.clg, HOMEPREMIUM.clg, PROFESSIONAL.clg, STARTER.clg, and ULTIMATE.clg. These files are located in the "sources" directory of the disc.

To open a .CLG file, you need to use the Microsoft Windows System Image Manager. This program allows you to view and manage the information contained in the .CLG file.
