Hey there, I'd be happy to help you.
Can you give me more details about what this file is, and which folder you put it in? I also don't really know what it means when you said you still have it in the original file location. What is the original file location? Is it a zip folder that you downloaded right away? If yes, what files are there in the folder?
Also, if the preset is for you to see and wear yourself, I think you need all the texture files and the material file used to make the preset, and put them in just one of the 12 "my_presets" folders.
Then you start up the game > go to preset maker > and export the preset yourself, so you can use the preset in-game like you want to.
