What is Other in Mac storage and how to remove it?

What is "Other" on your Mac's storage and how to remove or clear it?

Computer storage or disk space is the amount of data (measured in 'bytes') that a drive is capable of holding. Mac computer users can check how much disk space is available on their systems by clicking the Apple menu () at the top left of the screen and selecting "About this Mac", and then selecting the "Storage" tab. Despite this, even basic information can seem confusing at first, especially with regard to Mac hard drive categories. Mac users often become aware of disk space when a message stating that 'there is not enough free space' appears when downloading files from the Internet. When checking the status of storage on your system, you may notice the category "Other" occupies a great deal of space.

Files under this section may seem redundant, not important, and can be deleted, but we recommend that you read through this article before removing any files. Commonly, third-party applications invite you to clean the hard drive quickly, but if the "Other" category is targeted, you might lose important files. In fact, this particular section does store files that are junk files (for example, cache and temporary files), so you need to differentiate between those and the important files. In this article, we describe files listed under the "Other" category and show how to safely remove some unnecessary data.

What contains in the Other category?

Many users report that this confusing category consumes a lot of hard drive memory, thus prompting them to seek methods to clear the category or reduce the amount of space taken. Before proceeding, you must determine what data is hidden within this particular group of content. The title ('Other') can be misleading, since there are not only junk files, but also important personal files. Below, we clarify this category and include some examples of what 'Other' contains:

  • Common documents and file types, such as PDF, doc, PSD and some others.
  • Any type of compressed files, including disk images, zips, dmg, iso, tar and many more archive type files.
  • User's personal data.
  • Some files in the system folders of Mac OS, such as temporary files, swap, voices, etc.
  • Files such as application support, iCloud files, screen captures, and similar.
  • Cache items, including browser cache and locally-stored message media content.
  • Fonts, app accessories, application plug-ins, and extensions.
  • Various data and file types that are not recognized by Spotlight, such as virtual machine hard drive, Windows boot camp partition, and a number of other type files.

These files are just a small sample of those that might be contained within the Other category. You might prefer not to lose certain file types, whereas others can be removed without any particular consequences (for example, system caches, temporary files, and other junk files). So, the 'Other' category is a collection of data that includes miscellaneous file types not suitable for any other existing category. Now we have a clear view of this category, we can use methods to clean this group of junk files.

How to clear Other category on Mac running macOS Sierra or later

Some users believe that newer versions of the Mac operating system are well optimized and never run out of free space, but this is not actually correct. Although Sierra and later versions are much better optimized, these system do run out of free space, especially when small capacity hard drives are installed. Even if you are running a system with considerable hard drive space, overfilling it will result in reduced system performance. Fortunately, mac OS Sierra and all later versions include a useful feature called Optimized Storage. Once this tool enabled, the Mac will automatically cleans its hard drive from old or unused files by transferring data to iCloud. All files moved from your computer to cloud storage will be accessible through a website (from which you can later download them to your Mac). Additionally, if you experience significant loss of storage space on macOS High Sierra, read this guide.
