C disk space is getting less and less reasons to thoroughly check

Why is my C drive space getting less and less? Every time I started Windows Vista, I didn't do anything, and even uninstalled some software, I found that the C drive space was getting bigger. Is it equipped with Vista, the remaining space of the C drive is getting smaller and smaller, what is going on? How to solve the problem that the disk space of this C disk system is getting less and less? This issue is one of the top 10 common Windows Vista issues. The universality of this issue is well understood by everyone, so go directly to the topic and give you 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, pick up the scalpel and pull out the reason why the Vista C disk space is getting smaller and smaller, and completely eliminate this culprit. Remind everyone to note that this article uses the C drive to refer to the drive letter that installs Windows Vista. It is represented by the C drive. You can install Vista to other drive letters, and you can follow the gourd draw.
First, depth analysis 1, hiberid file hiberfil.sys: The file in the root directory of the C drive is a hidden system file, the hidden hiberfil.sys file size is exactly the same as your own physical memory, when you let the computer When entering hibernation, Windows Vista writes all 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, the sleep function can be selected. After testing, turning off this sleep function can free up 4G of space. Step 1: Safely delete the hibernation file under Vista: Run cmd.exe as the administrator to open the command line window, and then run: powercfg -h off. Note that the hidden hiberfil.sys file on the C drive can be unhidden and deleted directly. 2, virtual memory pagefile.sys: Windows system, including Vista, the default setting of physical memory 1.5 times the size, as a page swap file, if you are the size of the system management, then this volume is automatically changed, often bigger and bigger . 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, 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, and you will find that your entire Windows system is "flying". To set the 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. Application cache brought by Superfetch function: In Windows Vista system, the new technology features of Superfetch are used. For details, please refer to: Windows Vista SuperFetch/Prefetch technology, Vista optimization: teach you how to set Vista to start pre-reading and The application pre-reads these two articles. Cleanup method: Delete all the files in the c:\\Windows\\prefetch folder. 4. Temporary files generated by the application: Generally stored in the Windows\\temp folder, and in the temp folder of the user folder. Cleanup method: directly delete the files in c:\\Windows\\temp and C:\\Users\\your username\\AppData\\Local\\Temp folder. 5. Temporary files generated by browsers such as IE: Cleanup method: In the Internet option of the control panel, delete the cookie and IE temporary files. It is strongly recommended to use the one key in Vista Optimizer 2.0 to clear the Internet trace function, especially before the backup system. It is best to remove the clean. 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 a "snapshot" method to record the status information of the system at a specific time, which is called a "restore point", and then based on this information when needed. reduction. 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 reach 4G or even larger!
Turn off Vista's system restore 7, SP1 or automatically upgrade the patch package to generate a new backup of the system files. It is recommended that this does not need to move, keep it best. 8, Windows Vista system log and event log Generally in the Windows folder under the System32 folder LogFiles folder, directly delete is also ok.
