What is a COURSE file?
A .COURSE file is primarily a game data file used by The Golf Club, a popular golf simulation game developed by HB Studios. Players and developers use these files to store custom-designed golf courses. Internally, these files are compressed using the standard GZIP format to save disk space and make sharing easier. Another application that uses the .COURSE extension is Super Mario ReMaker, a fan-made game where the file stores custom-built platformer levels.
How to open COURSE files?
To play a .COURSE file in The Golf Club, you must place the file in the designated courses folder within the game installation directory. Because the primary format is a GZIP archive, you can also inspect the raw files by renaming the extension to .gz and extracting the contents with archiving tools like 7-Zip or WinRAR.
Software and tools
You need the specific game, such as The Golf Club or Super Mario ReMaker, to play the actual levels. To extract or view the raw data of the golf game variant, command-line tools like `gzip` or visual software like 7-Zip work perfectly because of the underlying GZIP compression.
Summary
viewer.online/course analyzes .COURSE files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because the .COURSE extension has multiple possible meanings, we recommend viewer.online/course to identify the actual format of your specific file. Because the most common .COURSE files use the known GZIP format, viewer.online/course can safely open and display them online, eliminating compatibility problems.
