What else is in the Mac hard drive?

1. View the "other" part size in OS X

Click on the Apple menu at the top and select "About this machine" item.

Next, select the Storage tab in the middle of the window. You can find a MAC computer's disk space distribution, the "other" part (blue) is relatively small.

2. What does the "other" section really have?

The "Other" section takes up more disk space, so what exactly are the "other" parts of those files?

OS X recognizes the types of files in your application, backup, audio, movies, backups, and photos, while the "other" section includes other file types that include the file types mentioned above. This means that the "other" section contains quite a few file types. The following list is common:

File and file types, including. pdf,. doc,. psd, and other file types

Archive files and disk images, including. zip,. dmg,. iso file types

Personal files and user data

Files within the OS X system folder, such as the system's temporary files, etc.

User library files, such as application support documents, ICloud documents, screensavers, etc.

User caching and system caching, such as browser caching and locally stored conversation information

Font files, application plug-ins, application extensions, and more

Spotlight unrecognized file types, such as disk drives for virtual machines, Windows boot Camp boot partition, etc.

As you can see, the files in the list above are files that are not necessarily cleaned up frequently. As long as it is an unrecognized file type for OS X, it is placed in the "other" section. While the "other" part of the file contains some cache and other garbage that can be cleaned up, there is no need for users to often use cleanup software repeatedly on MAC computers.

3. Reduce the burden to the "other" part

Generally speaking on a Mac, you don't need to focus on the "other" part of the disk footprint in real time unless you have a "low disk space" hint. If you want to try to clean up the "other" section of the file. You can start with 4 chunks to see what files you no longer need.

1, ~/downloads

2, ~/library/caches/

3, ~/documents/

4, "Information" application included in the attachment file

After seeing this, are you trying to get ready to delete the deletion? PC6 also want to remind again: before deleting them, be sure to do a backup first, use time Machine backup is the most convenient. After all, the "Other" section also contains a fairly large number of system catalogs (such as/system), and the blind modification of these directories can cause considerable trouble to your Mac.
