Vista C disk space is getting smaller and perfect solution

Why is my C disk space getting smaller and smaller? Every time I start Windows Vista, I have done nothing, and even uninstalled some software, I found that the C disk space has become even bigger. Is it equipped with Vista, the C drive will get smaller and smaller, what is going on? How to solve the problem of the C drive system disk space?

As one of the 10 common Windows Vista problems, this problem Universality, not to mention here, we go directly to the theme, and give everyone the perfect solution.

However, there are some system settings and optimizations involved. Although there is no danger, it is recommended that everyone look at it carefully. At the very least, you need to know the principles and methods to recover from the past. After all, Vista has some reason to take up the C drive space, it is still good for everyone's system, such as application cache and so on.

Next, let's take a look at the reason why the Vista C disk space is getting smaller and smaller, and completely eliminate this culprit.

Here to remind everyone, this article uses the C drive to refer to the drive letter of the Vista system installed, with the C drive, you install Vista to other drive letter (generally the C drive is the main system disk, such as To use the dual system, you need to consider the specific operation), and also according to the gourd painting.

First, deep analysis and solution

1, hibernate file hiberfil.sys:

The file in the root directory of the C drive is a hidden system file, hidden this hiberfil. The sys file size is exactly the same as your own physical memory. When you put the computer into hibernation, 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 canceled. After hiding, delete it directly.

2, virtual memory pagefile.sys:

Windows system, including Vista, the default setting of 1.5 times the physical memory size, as a paging exchange file, if you are the size of the system management, then, This volume is automatically changing and tends to grow larger. If your physical memory is relatively small, only 512m or 1g, you can choose to keep this file.

If you keep this file, we recommend that you put it in another partition, not with the C drive (system disk), otherwise, when you do Ghost or other backup, you still need Manually delete it. It is recommended that you specify the size and specify 1.5 times the Ram physical memory size.

If you are using an XP system and the 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" (if it is a Vista system, Still not recommended to close, more than 2.5G can be considered).

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.

3, the application cache brought by the Superfetch function:

In the Windows Vista system, the new technology features of Superfetch are used. For details, please refer to: Windows Vista SuperFetch/Prefetch technology. Vista Optimization: teaches you how to set up Vista to start read-ahead and application read-ahead.

Cleanup method: Delete all the files in the c:\\windows\\prefetch folder, or use the one key in Vista Optimizer to clear the system garbage.

4, temporary files generated by the application:

Generally saved in the windows\\temp folder, and the temp folder of the user folder

Cleanup method: direct Delete the files in c:\\windows\\temp and C:\\Users\\your username\\AppData\\Local\\Temp folder. Or use the one-click key in Vista Optimizer to clear system garbage.
5, IE and other browser generated temporary files:

Cleanup method: Control Panel Internet option, delete cookies and IE temporary files, it is strongly recommended to use Vista optimization master One key in 2.0 clears the Internet trace function, especially in the case of the backup system, it is best to delete it.

6, System Restore, System Volume Information folder:

System Volume Information folder, Chinese name can be translated into "system label information". This folder stores the backup information of the system restore.

"System Restore" is one of the most useful functions of the Windows operating system. It uses the "snapshot" method to record the status information of the system at a specific time, which is called the "restore point", and then in need Restore it based on this information. There are two types of restore points: one is automatically created by the system, including system checkpoints and installation restore points; the other is created by the user himself or herself, also called manual restore point. As the user's system time increases, the number of restore points will increase, resulting in less and less hard disk space, and finally be warned that "the disk space is insufficient." It is also the most easily occupied file in the system disk. For a long time, this file can be up to 4G or even larger!

7. System files generated by SP1 or automatically upgraded patch package New backup

It is recommended that you do not need to move, keep it best.

8, Windows Vista system log and event log
