This must be a very basic question: I have been trying to purge mail attachments lately to free up space. One by one, yup, got that one in a safe place, delete, nope, don't need this one, delete, etc. Having gone through a very lengthy purge I discover a) that many of these seem to have reappeared in the Mail Downloads folder in the library from which I deleted them, and b) many of the ones I deleted are now in an apparently new Downloads folder on the desktop. Sources online suggest Mail may place multiple versions of files in various places depending on what you do, which has left me confused. Using Catalina. I have had the downloads preference set to "remove after message is deleted" - does this not allow me to delete attachments?
