Picked Upload! This is a picked upload! It showcases some of the best talent and creativity available on MTS and in the community.
Update 03/03/2018 (2.2.300)
Hi friends! I apologize for my absence. Unfortunately I will not develop MCD.I don't have enough time and energy. I have to work hard to make money for moving to another city.
A small update with the removal of ads and networking features will be released soon. Also will be laid out the source code of the program. Anyone will be able to continue the development of MCD.

I hope someone may be able to continue to develop and make MCD the best program for The Sims 4,

Sincerely, Dmitry Tkachev. Your Russian friend

Hi, my name is DmitryMalfatto. I'm from Russia.
Here's my project, Mod Conflict Detector for The Sims 4. It's a powerful GUI tool for detecting and solving mod conflicts in the game. Allows you to get rid of trouble-making mods, empty mods, mods for another games, or technically-not-even-mods, that got in the Mods folder by mistake. I've been developing this program since February 2015, and now it's finally available not only in Russian, but in English as well!

Main Features:
  • Detect non-TS4 files;
  • Detect stray files (not *.package, *.zip et al, but something that doesn't belong in your Mods folder);
  • Disable (particular) mods;
  • Open file in s4pi;
  • Show file in folder;
  • Delete file(s) straight from the program;
  • Search for duplicate mods;
  • Analyse files (to find out exactly in what way they modify the game);
  • Copy conflicting ResourceKeys.

System Requirements:
  • Operating system: Vista, 7, 8, 8.1, 10*;
  • RAM: 1 GB
  • .NET Framework 4.6
* RT, Phone and Mobile editions are not supported

Additional Credits:
A big thanks and a special mention goes to:
  • adamhathcock for SharpCompress library;
  • creators of Microsoft.Windows.Shell.dll library;
  • creators of s4pi for the inspiration;
  • KuriXarya for the very idea of the program & help with Russian grammar;
  • Petr54 for the testing & ideas on how to improve the program;
  • Postoyalec [ToDoAbout on MTS] for the English translation.

This, too, is happening to me. I have windows 10. It brought up the "windows protected your pc" once, and since then, every time I try to open the program nothing happens at all.

Thank you /so/ much for making this!! I always have trouble knowing which .zip files are script and which aren't, and this helps so much!! <33333
#60 Old 6th Aug 2015 at 9:24 PM
I have used this, thanks. It is showing conflicts that are the same thing. Like hair cc, the conflict is coming up as the exact the same cc. Also there are conflicts from the same creators, like a top from cc creator PZC is in conflict with another top made by her.

Awesome program. Thanks!
And to those that get an exeption/crash when scanning, if you have your game open while using the program, that might be the problem. At least it was for me. As soon as I closed down my game, it worked fine.

Works great! Thank you! I was able to remove a lot of duplicates, conflicts, and Sims 3 files. Not sure how the Sims 3 files were working in the game, but I'd rather be safe and just remove them.
