OH ok sorry i had no idea lol thank you so much

so i downloaded forge before and had 50 or so mods and my pc became very slow and it was to the point where i couldnt open minecraft anymore so i reset my whole computer. and i just dowloaded minecraft and wanted to get all my mods back so i went to download forge, (1.15.2 newest version) and i downloaded it and tried to open the installer and it said something like "there is no app to open this file" and i dont understand whats happening becuase you dont need an app to open a .jar file and i did download forge from curseforge no other places and ive tried a bunch of times and this keeps happening. can someone please help me resolve this.

How do I do that

Actually the shader is in the mod folder but it’s not in the game only forge and Minecraft are loaded, did u put the shader in the wrong place? Is there a different mod folder where forge and Minecraft are and that’s where the shader goes?

So I did everything right and put the shader I want into the mod folder and it says 1 mod loaded when I’m in the game but when I go into my world the shader is not there, why is this happening?
