What is Other Storage on a Mac?

In short, Other storage contains all the files that do not match the specified standard categories displayed on the storage chart, such as Documents, Photos, Apps, Movies, Audio, etc. This is how Apple’s source explains the concept of Other Storage.

Other storage includes the following types of files:

  1. System temporary files
  2. macOS system folders
  3. Archives and disk images (.zip, .iso, etc.)
  4. Personal user data
  5. Files from the user’s library (Application Support, iCloud files, screensavers, etc.)
  6. Cache files
  7. Fonts, plugins, extensions
  8. Hidden files
  9. Other files that are not recognized by a Spotlight search

However, keep in mind that Other Storage does not always mean garbage, as there are some useful files kept in this category. This is why it’s a good idea to use a dedicated removal tool like MacCleaner Pro when reclaiming your disk space.

Why is my Other Storage so high?

If you have many applications and haven’t cleared their caches for a long time, if you keep all iCloud files on your Mac, if you save a lot of emails, then over time all these files can take up a significant amount of space in your Mac Other Storage. All applications create tons of temporary files, and not only caches. Applications have their own fonts, plugins, extensions and other service files. That’s why, if you have a big number of applications , your Other Storage might be high.

Where is Other Storage on a Mac

Most files in Other Storage are located in the hidden Library folder. Apple hides service files to prevent the deletion of important files that could cause problems with applications or system operations. So please, when clearing out the Library folder, resist touching any files if you don’t understand what they are used for, as it could be disastrous. We also recommend you perform a complete system backup before beginning.

Steps on how to find files from Other category in the Library folder:

  1. Open Finder.
  2. Click Go in the Menu bar.
  3. Select Go to Folder. Also, you can use the ⌘Cmd + ⇧Shift + G shortcut for this option.
  4. Type ~/Library in the search field and click Go.

Here you will find all the system and applications’ support files. As we mentioned above, system support files, caches and other service files are included in the Other category.

Steps on how to delete Other Storage on Mac

1. Clear cache from Other Storage

  1. Open the Finder.
  2. Press ⌘Cmd + ⇧Shift + G.
  3. Copy and paste the directory ~/Library/Caches.
  4. Hit Go.

    Go to the Folder search field

2. Remove installation files

By default, all files downloaded from the Internet are stored in the Downloads folder. Looking in here you’ll find installations, .pkg files and .dmg files that are no longer needed and can be deleted. So, to save space, explore the Downloads folder and remove all unnecessary files.

3. Remove extensions from Other storage

Extension files, such as plugins, installation files, screensavers and web browser extensions, can take up unnecessary disk space on your Mac. There’s also the factor that some extensions may have a negative effect on your system, noticeably slowing things down. If you can live without the features they offer, we recommend finding and getting rid of them.
