#5 Application Support and Caches

These 2 folders directly connected with applications maintenance installed on your Mac. In Applications Support apps create additional files required while running, and in Caches, there are specific files that are saved in case of repeatable access. Files are useful, but some may cause problems in the course of time:

  1. They left on an HD if you delete apps by putting them into the Trash.
  2. Some apps do not control the size of the files.
  3. In fact, they can slow down your apps.

Manually they can be deleted in the following locations:

~/Library/Application Support

As well you can use our free utility App Cleaner& Uninstaller, which allows you to delete system files, whole application or its remains if they have been deleted in a usual way.


Downloads Folder despite its impressive size goes to 4th place due to the fact that the human factor plays big role. Users often have to download files, that are used one-time and then files remain in the folder.
As well, it should be noted that such applications as browsers, messengers or download clients (µtorrent, MediaGet, JDownloader, etc.) as well by default save everything in Downloads.

Deleting contents of the Downloads folder does not differ from any other folder cleanup, but the removal of all unnecessary user files downloaded from the Internet isn’t a simple task. Read the article “How to Delete Downloads on Mac.”

#3 Apple Libraries

Even though in this section we speak about such applications as iTunes, Photos, iMovie and so on, it’s better to delete files not from the apps within, but folders where these files are collected. Why? Let’s see it on the iTunes example. Let’s say you have recorded something, downloaded it on your computer and added to iTunes. At this point, the app will copy your record in the library which is located at:

Macintosh HD/Users/[current user]/Music/iTunes Media/Music/{artist}/{album}

That’s why it makes sense to delete the original file. It’s much easier to search files with Disk Expert  ( see the screenshot above), which shows files and folders on your Mac in a form of pie chart diagram. As a result,  it’s much easier to find a big bulky content on Mac, like iTunes.

#2 Mail Attachments

With Mail, we considered all attachments once opened. As they are once downloaded to your computer, then you can view them. All photos, audio, video, PDF and other files, which users exchange often are stored in a hidden folder on their hard disk and occupy a lot of space.


The good news is that if you delete these files manually (not via Mail) they can be downloaded as needed from the e-mail server. Here’s a separate article about How to Delete Mail Attachments.

#1 Videos

The Movies folder has the following location Macintosh HD/Users/[current user]/Movies. It is the main place to store your videos, but Mac users often have such content elsewhere. Video files are one of the most severe types of files for ordinary users. To find video files use Disk Expert. Due to the fact that movie files are usually large and Disk Expert generates charts based on the size of files and folders – you can easily find and remove unwanted videos from your Mac.
