how do I remove an association?

[exekutive]

I had previously associated .nfo files with an application. I want these files to be just unrecognized generic files again, without any UTI entries. (it's a requirement for another extension I'm using)
Can this utility do that?

[Lord-Kamina]

I don't think that's possible. The only way for LaunchServices to forget a UTI is for all apps referring to it to go.

[Alkenso]

I think that would be a good option to 'erase' all assotiations with particular schema or UTI

Yup, really need a way to delete a URI entry and clear extraneous associated applications.

still no joy. this is totally messing up certain browser links for me. how to manually remove a custom URI scheme ??

Also would like to uncheck to delete the assignment.

I installed a browser I don't use. Made the URL link open in this browser, then uninstalled that browser. This worked!

I also then uninstalled this extension.
