How to delete a video mode>custom preset you created?

I’ve made many presets in the custom area in Video Mode. Some are the same preset that I’ve accidentally created. I want to delete some of them to clean out basically copies of a preset I’ve already done.

How can I do this?

I’ve looked in the program files to find these presets with the same name but are no where to be found other than the default ones that already come with the program.

It depends on your OS, which you did not specify. See the FAQ:

Then, look in the “profiles” folder.

Windows. But the FAQ helped thanks!
