CTRL + Delete can delete direct files

ClEANUP and optimization of fedora (transferred from http://tieba.baidu.com/p/1075262238)
Install the plug-in # Yum install Yum-Remove-with-Leaves 
Uninstall the software together with the dependency: # Yum remove ** -- remove-Leaves 
Clear old kernel: # package-cleanup -- oldkernels
Clear orphan packages that are no longer supported by the current software Repository: # package-cleanup -- orphans
Clean up the dependent packages that are not used by any software in the current system: # package-cleanup -- leaves
Install the cleanup software bleachbit, # Yum install bleachbot. noarch
After the installation is complete, run the root command on the terminal to open bleachbit, and then select options other than memory and disk space.
Disable SELinux, # Vim/etc/SELinux/config change enforcing to Disabled
Shut down the firewall # The setup command will pop up the system setting tool to disable the firewall. Some other services can also be disabled.

Then I don't feel any improvement...

Added music file tag garbled (http://www.linuxdiyf.com/bbs/thread-203110-1-1.html)
The perfect method is to modify the environment variable and modify the/etc/profile file as root:
Add the following two lines to the end of the file:
Export gst_id3_tag_encoding = GBK: UTF-8: gb18030
Export gst_id3v2_tag_encoding = GBK: UTF-8: gb18030
After cancellation, re-import the song information to solve the Garbled text.

After the experiment, some music files are still garbled, but most of the Chinese music labels are normal.
