another thing I found on desktop after updating OS X 10.15.5 so I copied and pasted below
During the last macOS upgrade or file migration, some of your files couldn’t be moved to their new locations. This folder contains these files.
Configuration files
These configuration files were modified or customized by you, by another user, or by an app. The modifications are incompatible with the recent macOS upgrade. The modified files are in the Configuration folder, organized in subfolders named for their original locations.
To restore any of the custom configurations, compare your modifications with the configuration changes made during the macOS upgrade and combine them when possible.
