It is always important to maintain as much free disk space as possible. You might not think about it but your Trash can accumulate quite a bit of disk space. Of course you can, and should, manually clean out your Trash on a periodic basis. However, we can all get absorbed in other things and before we know it, we have let the Trash grow to a significant size.
This is where setting up automatic file removal can be important. To set this up go to Finder >> Preferences >> Advanced. Check the box for “Remove items from the Trash after 30 days”. With this enabled, any files that have been moved to the Trash folder will be automatically permanently removed when they have been there 30 days. Any files less than 30 days old are left untouched.
