The GSR file extension is a “Golden Software Reference” file developed by Golden Software LLC. It is commonly used with mapping applications like Surfer. GSR files store data in a format specific to GIS mapping files. Files with this extension are most commonly used on Windows platforms, especially Windows 10.
We have tools that can open, view, convert, merge, split, and compare GSR files without needing to install other software. On your own computer though, if Windows does not recognize a .gsr file type, you will get a message to select an app to open the file. The .gsr format is not automatically associated with specific Windows apps. In that case, you can manually associate .gsr files to the appropriate software in the Windows Registry.
Many users have problems knowing how to open unfamiliar file types like .gsr. Hopefully this information helps explain what a GSR file is, what it’s used for, and options for opening or manipulating these files. Please let us know if you would like additional details on anything related to the .gsr file format.
