First, deep analysis and perfect solution
1, hibernate file hiberfil.sys:
The file in the C drive root directory for hidden system files, hidden this hiberfil.sys file size and its own physical The memory is consistent. When you put the computer to sleep, Windows Vista writes all the memory contents to the Hiberfil.sys file before shutting down the system. 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 is restored to its pre-closed state. Windows Vista does not delete this file, but keeps it on the hard disk, which will take up a portion of the disk space. With the sleep function, you can choose the sleep function, and the people of the Vista home team will shut down the hard drive. It takes up space and has to read and write hard disks frequently. The assassin's t61 is just four more G space.
Step 1: Safely delete the hibernation file under Vista: Run cmd.exe as the administrator to open the command line window, then run: powercfg -h off. Note that the hidden hiberfil.sys file on the C drive can be unhidden. Delete directly.
2, virtual memory pagefile.sys:

If your physical memory is relatively small, only 512m or 1g, you can choose to keep this file.
If you keep this file, we suggest that you put it in another partition, not with the C drive (system disk), otherwise, you will need to manually delete it when you do Ghost or other backups. . It is recommended that you specify the size and specify 1.5 times the Ram physical memory size.
If your memory is above 2G, we recommend that you turn off the virtual memory function directly. You will find that your entire Windows system is "flying".
How to set virtual memory: Control panel - Click on the system in the classic view, click on the advanced system settings on the left, click on the first setting (performance), then click on Advanced, in the virtual memory, click on Settings. Note that the hidden filefile.sys file on the C drive can be removed directly after unhiding.
