　　2, delete System Restore, that is, Systems Volume Information folder

System Restore, that is, systems Volume information folders occupy a large C disk space, as users increase the use of system time, C-disk storage System Restore files (used to restore to a certain point in time before the exception) will be more and more, resulting in less hard disk space, Finally, you will be warned about "insufficient disk space." It is also the most easy to occupy a space in the system of a file, a long time, this file size up to 4G, or even bigger!

If your physical memory is larger, 4G or more, you can delete this file.

If you keep this file, we recommend that you put him in another partition, not to the C disk (System disk), otherwise, when you 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.

How to set virtual memory: Right click on "Computer

The file in the C-packing directory for hidden system files, the hidden Hiberfil.sys file size just and their own physical memory is the same, when you put the computer into hibernation, Windows7 the system before shutting down 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.

Can Windows7 this file will not be deleted, but has been placed on the hard disk, will be in vain to occupy a portion of the disk space, long time your hard disk can be too much. Have a sleep function can be, sleep function can choose not, 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 a hibernation file: Run Cmd.exe with an administrator to open a command line window and then enter: Powercfg-h off, run.
