Find Configuration Files.

After a recent Big Sur update, I have finished up with a blue folder on my desktop named as Relocated Items. Clicking on the folder shows the following message;

"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 customised by you, by another user or by an app. The modifications may be incompatible with the recent macOS upgrade. The modified files are in the Configuration folder, organised in subfolders named after 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. 

Configuration files with the suffix "system_default" were edited or customised but the changes were allowed to remain installed. The system_default version of the file is provided to demonstrate what the Apple-supplied version of this file would look like. It is recommended you compare the two and evaluate whether you wish to integrate any changes Apple may have made to the default version. "

Can anyone please tell me how and where I can find the Configuration files? I am puzzled because I am not aware of any changes I have made.
