Delete Mail Downloads is an easy way to clear junk file for mac, targeting leftover email attachment cache files.

How to clear junk file for mac

Step 1: Open Finder.

Step 2: Click Go → Go to Folder, or use the keyboard shortcut Cmd + Shift + G.

Step 3: Enter the following path:

Finally, delete all contents within this folder to clear out old email attachments.

Pros

  • Quickly frees up 1–5 GB of local storage space.
  • Only clears cached attachments; does not affect your email account data.

Cons

  • If you want to view deleted local attachments again, you’ll need to download them again.
  • Since new attachments accumulate over time, you’ll need to clean them up manually on a regular basis.

This is one of the most convenient built-in methods for clearing junk files on a Mac; it’s perfect for quickly freeing up disk space without posing any risk to the system.
