Deleting a Thread with attachments

[New Joe]

If I delete a Thread which has a lot of PDF attachments on it, does that automatically delete them from my cPanel on my hosting too?

Reason I ask is I have a Thread with a lot of big files and I want to clear them out so thought I'd just delete the Thread but it crossed my mind will that also delete them within my hosting cPanel

The attachments will be removed from the file system via a routine cron task.

Is that something I have to do or is it automatically done?

It's done automatically.

It's done automatically.

Can this cron be disabled if we don't want attachments deleted?
