Jul 19, 2017 By default, the Mail app on your Mac downloads all email attachments you receive to the computer, eventually taking some serious amounts of storage space. As we’ve seen in the past, there is a way to tweak this and stop the Mail app from downloading all attachments, but it will still locally download attachments that you open.
If you're running low on disk space on your Mac, especially SSD space, every extra bit can count. One of the places you can often scrape out a few extra megabytes or even gigabytes is Mail Downloads. Any attachments you open in Mail or Quick Look gets saved right to that folder. Chances are you don't need them, especially the old ones, and trashing them will free up some valuable space.
How to find and delete old Mail Download files to free up space
- Open Spotlight Search
- Type in Mail Downloads and click on the folder when it shows up to open it.
- Here you'll see a list of files that Mac Mail has saved. These are all attachments that you've either opened in Mail or viewed in Quick look.
- Delete the files you don't need and then close the Mail Downloads folder.
- Aug 08, 2017 Since the release of Mac OS X, Mail.app has been the default email application. Mail stored emails in.mbox files up until the release of Mac OS X Tiger 10.4, at which point Apple changed the default file type to.emlx. When looking for an email on Mac OS X drive, the standard location for the stored email is in a hidden user library.

Sep 13, 2006 #1 I am trying to write documentation for Mail.app, but whenever I delete /Library/Mail and go to re-enter my settings, I notice that some things are kept, such as the SMTP Server List, whether or not the incoming or outgoing server uses SSL, etc.
If you send and receive a lot of email, it's very easy for the Mail Downloads folder to get extremely large. Checking it every few weeks or months, whatever is appropriate for your use case is a good idea.

Optimized Storage in macOS Sierra and later* can save space by storing your content in iCloud and making it available on demand. When storage space is needed, files, photos, movies, email attachments, and other files that you seldom use are stored in iCloud automatically. Each file stays right where you last saved it, and downloads when you open it. Files that you’ve used recently remain on your Mac, along with optimized versions of your photos.

- The Storage pane of About This Mac is the best way to determine the amount of storage space available on your Mac. Disk Utility and other apps might show storage categories such as Not Mounted, VM, Recovery, Other Volumes, Free, or Purgeable. Don't rely on these categories to understand how to free up storage space or how much storage space is available for your data.
- When you duplicate a file on an APFS-formatted volume, that file doesn't use additional storage space on the volume. Deleting a duplicate file frees up only the space required by any data you might have added to the duplicate. If you no longer need any copies of the file, you can recover all of the storage space by deleting both the duplicate and the original file.
