Customizing the Location of Git Global Configuration Files on Windows: Methods and Best Practices
This article provides a comprehensive analysis of methods to change the storage location of the Git global configuration file .gitconfig on Windows systems. By default, Git stores this file in the user's home directory, but users may prefer to relocate it to a custom path such as c:\my_configuration_files\.
