Getting rid of “Other” files on Mac

To get started and find out if the problem of cluttered “Other” storage is that serious for your Mac, you should check its memory usage. To do this, you should:

Go to the menu bar and click on the Apple icon

Choose About this Mac

Open Storage

If “Other” storage consumes more space than the rest of the storages, it’s definitely time to clean it. To do this correctly, you should know what type of files refer to the category “Other.”

Apple defines such files as those that don’t match any of these types:

Temporary files and System macOS folders

Personal data of user


Archives and disk images in formats .iso, .zip, etc

Documents in the formats .doc, .psd, PDF-files, etc

User’s library files (iCloud files, screensaver, apps support, etc.)

Fonts, extensions, plugins

All other types of files that Spotlight search doesn’t recognize

As you see, macOS tends to send any files that are not photo, music, video, application, certain type of documents, or at least an extension or a backup into “Other” storage. To regain some memory on your Mac, you should delete useless “Other” files from the hard drive. Since not all files labeled as “Other” are clutter, you should know some rules how to do a cleanup among them properly. Further down, we offer you three ways to delete some of “Other” stuff along with some helpful recommendations.

Method 1

In the Finder, click ⌘Cmd + ⇧Shift + G. Next, visit each of the following folders, by typing their names into the entry field:

  • ~/Downloads;
  • ~/Library/Caches;
  • ~/Documents/Logs.
choose caches folder
files in caches folder

Such files as installations, downloads from the Internet, .dmg, .pkg files, etc. are stored in these three folders by default. Delete from them all data that you believe is unnecessary.

Remember one simple rule: delete only files which you know! If you aren’t sure what the content of some file is, just let it be. By mistake, you can damage some important piece of data that may cause further bugs, glitches, and freezes on your Mac.

Method 2

Here’s one way of detecting “Other” files that can be carried out through the Smart Folder Finder. Press ⌘Cmd +F, and proceed with the search in “This Mac.” Choose “Other” folder among all options.

Tick “File size” in the window that opens, then press “OK.”

After you specify the size of a file, the list of searched files will open. Select and delete all unwanted ones.

choose other folder
click file size
unwanted files

Method 3

To make the process of sweeping out unwanted “Other” content less time-consuming, you may use a third-party app to help you. Such tools are easy and effective to use. The may also aid if you haven’t reinstalled your Mac clean for a long while, and many apps have created large folders overfilled with system files. Reinstalling such apps will help you to regain disk capacity.

As the free space lack issue especially relates to Mac laptops, let's examine how to clean up “Other” storage on MacBook Air.

First of all, you should check how much memory is taken by “Other” data. Ways of deleting such files described above work for MacBook Air as well. We gather some useful tips to help you carry out the process efficiently.

  • Delete trash from all multiple trash bins on your Mac. For example, Photos have their own Trash bin where deleted files are kept in until it's emptied.
  • Backups for iPhone and iPad, stored in MobileSync, may take a lot of space. Clean all but the latest backups.
  • iTunes is known for consuming quite much space. Open iTunes – Preferences – Device, and clean all backups except for the latest one.
  • Be sure to check your Downloads folder and your Desktop for any files you can delete, as the content of these folders is mostly labeled as “Other.”
  • In case you receive large email attachments that also refer to “Other,” you may want to clean them up.

We hope that our recommendations will help you to deal with “Other” storage easily and effectively.
