You don't know the C-disk space cleanup skills

first, the depth analysis

1, the SuperFetch function brings the application cache:

In Windows Vista system, using the new technology features of SuperFetch, please refer to Windows Vista superfetch/prefetch technical details, Vista optimization: teaches you how to set up Vista startup pre-read and application pre-read these two articles.

Cleaning method: Directly Delete all the files in the C:/windows/prefetch folder.

2, dormant 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 physical memory, when you put the computer into hibernation, Windows Vista before shutting down the system to write all the memory content to the 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 returns to its state before it shuts down. Windows Vista does not delete the file, but it is always on the hard disk, which takes up a fraction of the disk space. With the sleep function, the Hibernate function can choose not to download the latest XP system. After testing, turn off this hibernate function to empty out 4G of space.

Vista Security Remove hibernation file under the admin as the Administrator run Cmd.exe open the Command Line window, and then run: powercfg-h off, note that the C disk residue Hiberfil.sys hidden files can be removed directly after the deletion.

3, virtual memory Pagefile.sys:

Windows system, including Vista, defaults to 1.5 times times the size of physical memory, as paging Exchange file, if you are the size of the system management, then, this volume is automatically changed, often more and more large. If you have less physical memory, only 512m or 1g, you can choose to keep the file.

If you keep this file, we recommend that you put him in another partition, not with C disk (System disk) together, otherwise, you will do ghost or other backup, or you need to manually delete it. It is recommended that you specify the size and specify 1.5 times times the ram physical memory size.

If your memory is above 2G, we recommend that you turn off the virtual memory function directly, and you will find that your entire Windows system is "flying".

How to set up virtual Memory: Control Panel-The classic view inside the click System, click on the left Advanced system settings, click on the first setting (performance), and then click Advanced, in virtual memory there, click Settings. Note that the C-disk residual pagefile.sys hidden files can be removed directly after being hidden.

4, the application generated temporary files:

Typically saved in the Windows/temp folder, and in the Temp folder of the user's folder.

Cleaning method: Directly to the c:/windows/temp and c:/users/your username/appdata/local/temp folder in all the files can be deleted.

5, IE and other browsers generated temporary files:

Cleaning method: Control Panel Internet Options, delete cookies and IE temporary files, it is strongly recommended to use Vista Optimization Master 2.0 of a key to clear the Internet traces, especially the backup system before the best removal of clean.

6, System Restore, Systems Volume Information folder:

The System Volume Information folder, the Chinese name can be translated as "systems volume label information." The backup information for System Restore is stored in this folder.

System Restore is one of the most useful features of the Windows operating system, which takes snapshots to record the state information of a system at a given time, known as a "restore point," and then restore it based on that information when needed. There are two types of restore points: one that is created automatically by the system, including system checkpoints and installation restore points, and the other is the user's own creation, also called a manual restore point. As users increase their use of system time, the restore points will become more and more, resulting in less hard disk space, and finally be warned that "insufficient disk space." It is also the most easy to occupy a space in the system disk of a file, a long time, this file size up to 4G, or even bigger!

7. Windows Vista system logs and event logs

Generally in the Windows folder under the System32 folder inside the LogFiles folder, the direct deletion is OK.

8, SP1 or automatic upgrade of the patch package generated by the new backup of the system files

Suggest this is not moved, keep it the best.
