Ubuntu uses **[APT Command][5]** (Advanced Package Tool) for package management like installing, removing, searching, etc,. Ubuntu 使用 **[APT 命令][5]** (高级软件包工具)用于软件包管理，像：安装，移除，搜索等等。
By default every Linux operating system keeps a cache of downloaded and installed packages on their respective directory. 默认情况下，每个 Linux 操作系统在它们各自的命令保留下载和安装的软件包的缓冲。
Ubuntu also does the same, it keeps every updates it downloads and installs in a cache on your disk. Ubuntu 也做相同的事，它以缓冲的形式在你的磁盘上保留它下载和安装的每次更新。
Ubuntu system keeps a cache of DEB packages in /var/cache/apt/archives directory. Ubuntu 在 /var/cache/apt/archives 目录中保留 DEB 软件包的缓冲文件。
Over time, this cache can quickly grow and hold a lot of space on your system. 随着时间推移，这些缓存可能快速增长，并在你的系统上占有很多空间。
Run the following command to check the current utilization of APT cache. 运行下面的命令来检查当前 APT 缓存文件的使用率。
``` ```
$ sudo du -sh /var/cache/apt $ sudo du -sh /var/cache/apt
147M /var/cache/apt 147M /var/cache/apt
``` ```
It cleans obsolete deb-packages. I mean to say, less than clean. 它清理过时的 deb 软件包。我想说，一点都清理不干净。
``` ```
$ sudo apt-get autoclean $ sudo apt-get autoclean
``` ```
It removes all packages kept in the apt cache. 它移除所有在 apt 缓存中的软件包。
``` ```
$ sudo apt-get clean $ sudo apt-get clean
``` ```
### 4) Uninstall the unused applications ### 4) 卸载不使用的应用程序
I would request you to check the installed packages and games on your system and delete them if you are using rarely. 我可能要求你来检查在你的系统上安装的软件包和游戏，，删除它们，如果你很少使用。
This can be easily done via “Ubuntu Software Center”. 这可以简单地完成，通过 “Ubuntu 软件中心”。

The cache folder is a place where programs stored data they may need again, it is kept for speed but is not essential to keep. It can be generated again or downloaded again. 缓存文件夹是程序存储它们可能再次需要的数据的地方，它是为速度保留的，而不是必需保留的。它可以被再次生成或再次下载。
If it’s really filling up your hard drive then you can delete things without worrying. 假如它真的填满你的硬盘，那么你可以删除一些东西而不用担心。
Run the following command to check the current utilization of APT cache. 运行下面的命令来检查当前 APT 缓存的利用率。
