Can anything else on the Mac disk be deleted?

1. View the "Other" section size in OS X

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

Then select the "Storage" tab in the middle of the window. You can find the disk space distribution of your Mac computer, and the "Other" section (blue) is relatively small.

2. What is the "other" part?

The "other" portion of disk space tends to be small, so what exactly are those files that make up the "other" part?

OS X identifies centralized file types such as application, backup, audio, movie, backup, and photo, 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, and other file types

Personal files and user data

Files within the OS X system folder, such as temporary files for the system

User library files, such as application support documents, ICloud documents, screensaver programs, and more

User caches and system caches, such as browser caches and locally stored dialog messages

Font files, application plugins, application extensions, and more

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

As you can see, the files in the list above are files that do not need to be cleaned up frequently. As long as the file type is not recognized by OS X, it is placed in the "other" section. Although the "other" sections above contain some caches and other garbage that can be cleaned up, it is not always necessary for users to use cleanup software repeatedly on MAC computers to clean up.

3. Reduce the burden on the "other" part

Generally speaking on a Mac, you don't need to pay attention to the disk footprint of this "other" section in real time unless you are prompted with "out of disk space." If you want to try to clean up the "other" section of the file. You can start with 4 chunks and see what files you no longer need.

1, ~/downloads

2, ~/library/caches/

3, ~/documents/

4. Attachment files included in the "info" app

When you see this, are you trying to be prepared to delete the deletion? PC6 to remind you again: before deleting them, be sure to make a backup first, using Time machine backup is the most convenient. After all, the "Other" section also contains a large part of the system directory (such as/system), and the blind modification of these directories will probably cause considerable trouble for your Mac computer.
