How do I delete multiple PRESETS at once!?

[Ryan25575726vb6c]

I'm having a hard time trying to figure out how to delete multiple presets at once. I'm referring to the custom/user presets that I have made myself. I am using LR not LRC and I can right click individually to delete a preset. However I have hundreds of presets and it would take me way too long to individually delete them all.

Thanks in advance for any help,

Ryan

I don't think you can delete multiple presets all at once.

I'd  second that, as far as I know it's a one at a one operation.
