A method to deal with shrinkage of Win7 C disk space

First, the depth analysis and the perfect solution

1, 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 7 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 7 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 can be, the sleep function can choose not to, the team of people all shut down this hard drive large. Also occupy space, but also frequently read and write hard disk. The Assassin's t61 is so much more than 4 g of space. How to safely delete hibernation files under Windows 7 one: Run Cmd.exe with an administrator to open a 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 hidden file.

2, virtual memory Pagefile.sys:

Windows system, including Windows 7, defaults to 1.5 times times the size of physical memory, as a paging Exchange file, and if you are the size of the system management, then this volume is automatically changing, often getting bigger. 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.

3, the SuperFetch function brings the application cache:

In the Windows 7 system, using the technical features of Vista SuperFetch, please refer to the Windows WIN7 Superfetch/prefetch technical details to teach you how to set up WIN7 to start the read and application prefetching of the two articles.

Cleaning method: Directly Delete all the files in the C:windowsprefetch folder.

4, the application generated temporary files:

Typically saved in the Windowstemp folder, and in the Temp folder of the user's folder

Cleaning method: Directly to the c:windowstemp and c:users your username Appdatalocaltemp 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, especially if the backup system before the best delete 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.

Restore points are divided into two categories:

One is automatically created by the system, including system checkpoints and installation restore points, and the other is the user's own creation as needed, 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, the automatic upgrade of the patch package generated by the system files of a new backup

Suggest this is not moved, keep it the best. And if you want to delete it, it's okay.

8, Windows 7 system logs and event logs

Generally in the Windows folder under the System32 folder inside the LogFiles folder, directly delete also OK

9, NTFS partitions can be compressed, choose to ignore All.
