What is a CLG file?
A .CLG file is a data file that serves multiple different purposes depending on the software that created it. Often, it is a Windows Catalog File or a Windows Image Catalog file used by Microsoft to store component installation data. In other cases, a .CLG file is a plain text log file. It can be a change log used by Oracle Primavera project management software, a game crash log for games like Age of Wonders 4, or a diagnostic log generated by the MediaTek Catcher tool. Additionally, some photo collage programs save layout projects using the .CLG format.
How to open CLG files?
Because the .CLG extension has multiple possible meanings, you must identify the file type before you can open it correctly. If the .CLG file is a simple log file, you can open and read it using a standard text editor like Notepad or Visual Studio Code. If it is a saved collage project or a binary Windows Catalog File, you will need the specific creator software to open it.
