To teach you to clear WIN7 's C-Disk trash.

The WIN7 system uses the C disk will become more and more large, free space becomes smaller, disk cleanup, and security guard how clear also can not clear these system depth of garbage. We can delete it manually and free up the C-disk space.

As a result of this cleanup, my C drive freed up nearly 10 gigabytes of space.

The following methods can not be said to be effective for everyone, because each person on the computer with the software is not the same, if you also use the following software and I would like to try.

1 , hibernation file Hiberfil.sys:
The file in the C Packing directory for hidden system files, the hidden Hiberfil.sys file size is exactly the same as their own physical memory, when you put the computer into hibernation, Windows7 before shutting down the system to write all the memory content Hiberfil.sys file. Then, when you turn the computer back on, the operating system uses Hiberfil.sys to put all the information back into memory, and the computer reverts to the state before it was closed. Can Windows7 will not delete this file, but always put on the hard disk, will take up a portion of the disk space, long time your hard disk can be too much. With the sleep function can be, sleep function can choose not to, with his words, he is a big hard disk. Also occupy space, but also frequently read and write hard disk.
Windows7 the following methods for safely deleting hibernation files : Run Cmd.exe as Administrator, open a command-line window, and enter: Powercfg-h off, run.

Note that the Hiberfil.sys hidden files in the C drive can be removed and deleted directly, with a space in front of-H off.

2 , virtual memory Pagefile.sys:

Windows system, including Windows 7, defaults to 1.5 times times the size of physical memory, as paging swap files, if you are the size of the system management, then this volume is automatically changed and tends to grow larger. If your physical memory is relatively small, only 2g, you can choose to keep this file.
If you keep this file, we recommend that you put it in another partition, do not put it in the C drive (System disk), otherwise, you will be ghost or other backup time, still need to manually delete it. It is recommended that you specify a size of 1.5 times times the ram physical memory size.
If your memory is above 4G, you can consider turning off the virtual memory function directly. About being able to shut down virtual memory always wood has a clear verdict.

　　How to set virtual memory: Right-click on the computer

"- Properties-Advanced system Settings-advanced-settings (this is the performance item below)-Advanced-Change-click on C-Drive (automatic management ...) Previous box selected)-Radio "no Paging File (N)"-"settings", the virtual memory in the C drive disappears, then check d, select Custom Size-Enter the value in the initial size and maximum two text boxes below-"Settings"-OK-reboot, and the settings are complete.

3 , the SuperFetch feature brings the application cache:
In the WINDOWS7 system, the use of Vista SuperFetch technical features, the specific situation can be viewed on the Internet, the following only talk about cleaning methods.

4 , application-generated temporary files:
Typically saved in the Windows\Temp folder, and in the Temp folder of the user folder.

5 , IE and other browser-generated temporary files:
　Cleanup method: Open the browser, tools-internet options--Browsing history below Click Delete, delete cookies and IE temporary files can be, especially the backup system is best removed before the clean.

6 , systems restore, System Volume Information folder:
Systemvolume Information folder, the Chinese name can be translated as "System volume label Information". This folder stores the backup information of the System Restore. System Restore is one of the most useful features of the Windows operating system, which uses "snapshots" to record the status of the system at a specific time, known as a "restore point," and then restore it as needed. There are two types of restore points: One is automatically created by the system, including system checkpoints and installation restore points, and the other is a manual restore point that users create themselves as needed. As users use system time increases, restore points become more and more, resulting in less disk space and, finally, a warning of "insufficient disk space". It is also one of the most space-consuming files in the system disk, with a long time, this file size can be up to 4G, even larger!

Cleanup method: directly turn off System Restore! Right-click on "Computer"--Properties--Advanced system settings--System Protection--click on the C drive--configuration--Restore settings The following three options directly select the last "Turn off system Protection"--delete--continue--OK.
