I have been using Win7 for a while, but I found that my C drive space is getting less and less? Every time I started Windows 7, I didn't do anything, and even uninstalled some software, I found that the C drive space became bigger. Is it possible to install Win7, C disk will get smaller and smaller, what is going on? How to solve the problem of the disk space of this C disk system?
As one of the 10 most common questions Windows7, the universality of the problem, this is not to say, we go directly to the theme, and gives 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, Win7 has some reasons for taking up C drive space, and it is good for everyone's system, such as application cache. Next, pick up the scalpel and pull out the reason why the Windows 7C disk space is getting smaller and smaller, and completely eliminate this culprit.
draw attention to this paper refers to the C drive to install Windows7 of that letter, the representative of the C disk, you install Win7 to another letter, also shining painted gourd dipper line.
a depth of analysis and the perfect solution
1, hibernation file hiberfil.sys:
the file in the root directory of C for the hidden system files, hidden this hiberfil The .sys file size is exactly the same as your own physical memory. When you put the computer into hibernation, Windows7 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 7 does not delete this file, but keeps it on the hard disk and will take up some disk space in vain. With the sleep function, you can choose the sleep function, and the 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. Windows7 safely delete the hibernation file method: Run cmd.exe as the administrator to open the command line window, and then run: powercfg-hoff, note that the hidden hiberfil.sys file in the C drive can be unhidden and deleted directly.
2, the virtual memory pagefile.sys:
Windows system including Windows7, the default setting of 1.5 times the size of physical memory, as paging swap file, if you are the size of 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, 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".
set the virtual memory approach: Control Panel - Classic View click inside the system, click on the left side of the Advanced System Settings, click on the first set (performance), and then click Advanced, Virtual Memory in there, click Settings.
note, C drive residual pagefile.sys hidden file can unhide, direct delete.
3, Superfetch feature brings the application cache:
Windows7 system in which, to use the technical characteristics of VistaSuperfetch, details, please refer to: WindowsWIN7SuperFetch /Prefetch technology explain, teach you how to set up Win7 starts both pre-reading and application pre-reading.
clean-up methods: directly to the c: Windowsprefetch folder of all the files can be deleted.
4, temporary files generated by the application:
typically stored in Windows emp folder, and
Methods for cleaning up temp file in the user folder: directly c: Windows emp and C: Users your files in the AppDataLocalTemp folder can be deleted.
5, temporary files IE and other browsers generated:
clean-up methods: Control Panel Internet Options inside, and delete cookie IE temporary files can, in particular, the best backup system before it is deleted Clean.
6, System Restore, SystemVolumeInformation folder:
SystemVolumeInformation folder, the Chinese name can be translated as "system volume 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.
restore point is divided into two:
one is automatically created, including checkpoints and installing the system restore point; the other is the user-created as needed, 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!
7, the system automatically upgrade patch files generated by the new backup
suggests that this would not move, keep it the best. If you want to delete it is also possible oh
8, Windows7 system and event logs
general file in the Windows System32 folder under the LogFiles folder inside, ok also delete the < BR>
9, NTFS partition can be compressed, choose to ignore all. All software
even in Bahrain, it took more than 7G
two, C disk space LJ automatically cleared, expand the C drive space
