Fantastic. Thank you so much @Streetwind ! Once again, you have assisted another player.
For those following this, I found the clientsettings.json file in the VintageStoryData folder after I moved it. I opened it and went to the very end, locating the entry entitled ""modPaths" and changed what had been there to the accurate drive, in my case, "D:\\Vintagestory\\VintageStoryData\\Mods"
