I will show you 2 easy ways to remove mods in GTA V (Epic Games).. You can choose the method you like after reading this blog post.
Method 1: Compare and delete mod files
This image is a screenshot of the GTA V Epic Games vanilla folder. Compare your game folder (Epic Games\GTAV) with this image, and delete any extra files.
Once the deletion is complete, verify the game files in the launcher. That’s it. Your game is now vanilla.
Method 2: Delete everything except big files
Open your Game folder. Press Ctrl + A on your keyboard to select all the game files.
De-select the following:
.egstore folder, update folder, x64 folder, and all the .rpf files
You can delete the remaining files (which are highlighted in the above screenshot)
Once the deletion is complete, just verify to get the missing small files. Around 400 megabytes will be downloaded, and you will have a vanilla GTA folder post verification.
That’s how easy it is to make GTA V Vanilla.
