I've already backed up my configuration settings, but I'm not sure how to back up my favourite servers and profile data. I googled the location and found a few old threads claiming that the CS1.6 configuration settings are stored at C:/Program Files/Valve/cstrike/config.
I'm about to do a clean install of Windows 11 and wanted to back up the CS1.6 non-steam version settings, config, and data.
