Developer: Microsoft Corporation
File type: Windows Catalog File
You're here because you have a file that has a file extension ending in .clg. Files with the file extension .clg can only be launched by certain applications. It's possible that .clg files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .clg file?

Files affixed with the CLG extension are known as Windows catalog files and are categorized as settings files. Settings files contain data that may be used by Microsoft Windows systems or installers of a Microsoft Windows OS when a user accesses certain features associated to the details saved in those files. The Windows System Image Manager application, also known as Windows SIM, uses the content of these CLG files to describe the data stored in an image file with the WIM extension. These details stored in a CLG file refer to components and packages included in the image file, and this data is referenced by Windows SIM to display relevant information to the user without being required to access the actual data stored in the image. These CLG files are mostly included in Microsoft Windows distribution packages and are usually stored in installation disks. A CLG file that corresponds to a particular WIM image usually has a far smaller size than the associated WIM file.

Microsoft Windows System Image Manager

Microsoft Windows System Image Manager

Windows System Image Manager (Windows SIM) quickly generates and manages unattended Windows Setup answer files in a graphical user interface (GUI). Answer files are XML-based files that are utilized during Windows Setup to configure and to modify the default Windows installation. Windows SIM uses the content of CLG files to give details in the data saved in an image file having a WIM extension. It validates the settings of an existing answer file against a Windows image (.wim) file, and views all the configurable component settings in such file. It can update an existing answer file easily and creates a configuration set that contains a complete set of portable folders with setup files; and adds third-party drivers, applications, or other packages to an answer file. Those details are the components and packages in the image file and such data is referred by Windows SIM to show the information even if with no access to the actual data stored image. CLG files are packed in the Microsoft Windows installation disks.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .clg. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
