Improving Game Loading Times by Trimming Mod Folders
Locating the Pack Contents
Because this compilation provides classic textures for over 180 mods, it contains a large volume of texture data. If you are only playing with a few of these mods, you can delete unused folders inside the pack to significantly speed up your game's loading screen.
1. In Minecraft, navigate to Options > Resource Packs.
2. Click the Open Pack Folder button at the bottom left to view your resourcepacks directory.
3. If the resource pack is stored as a .zip archive, extract it into a standard folder so its internal files can be edited directly.
Removing Unused Folders
1. Open the unzipped pack folder and navigate to the assets folder.
2. Inside assets, you will find subfolders named after each supported mod.
3. Compare this list to the mods actually installed in your instance.
4. Select and delete any folders belonging to mods you do not have installed.
After removing the surplus folders, return to the game and press F3 + T to reload your resource packs. Minecraft will now load much faster because it only processes files for the mods you actually play.
