Many people find that after Bahrain win7 system, even if not installed any application C disk space has reached more than 10G. In fact, there are many things that we do not need these things removed from our computer, the point will not affect the system, but also greatly reduces the space. The following came to see how the savings of our hard disk space.
General After installation Windows 7 will occupy 10G-15G of hard disk space
1. Remove hiberfil.sys Hibernation File
Many people do not figure out what is the computer sleep. In fact, the computer has two low-power operating state, sleep and sleep. We used the sleep function of the computer, that is, one does not have a certain time, to enter a low power state, work attitude stored in memory, the recovery can be resumed 1-2 seconds to original working condition. This feature is very useful and the most commonly used. Dormant state, however, is to work all the memory information is written to the hard disk to 4G of memory, for example, that is, to write the 4G file to your hard drive before shutdown. Power to restore the files to be read into memory 4G, in order to restore the original working interface. The 4G file read and write take a lot of time, has no less than the normal boot, so now the hibernate feature very useful.
The dormant HIBERFIL.SYS this file is saved to memory when the dormancy state of use. C drive will occupy the same memory space (in 4G memory, for example, this file also for 4G), it can be deleted without affecting the people to use.
How: The administrator privileges to run CMD, hit the following command: POWERCFG-H OFF automatically delete the file.
2. The right to set the virtual memory
The role of memory in the computer much, the computer needs of all running programs memory, or if the implementation of the program very much, it will lead to memory exhausted. To solve this problem, WINDOWS use of virtual memory technology, which set aside hard drive space to act as memory usage, this part of the space is called virtual memory, virtual memory on the hard disk in a form that is PAGEFILE.SYS the page file. Virtual memory is physical memory to add, so do not be deified, virtual memory read and write performance (that is hard to read and write speed), only a few physical properties of one-tenth of the memory, and high frequency of read and write operations on large hard disk injury ! prone to hard disk damage! can not be without, to use less is less! principle is to stay small enough + margin can be.
Win7 system environment, the general 512MB of memory, according to the actual use of memory footprint, you can set virtual memory to 512-768MB (RAM + virtual memory of, and generally higher than the normal occupation of 256MB can be). 1GB memory, according to the actual memory occupancy, you can set virtual memory to 128-512MB (RAM + virtual memory of, and generally higher than normal occupancy can be 256-512MB). 2G RAM and above, generally can disable virtual memory (with software limits can be set up a small amount of virtual memory, such as 128MB). Some are indeed people who use lots of memory, such as large-scale 3D game play, making sharp images, 3D modeling, and received a warning system memory, and only need to increase the virtual memory as appropriate.
Generally first disable virtual memory, reboot the computer into Safe Mode (Do not run a large number of procedures), and then defragment, re-set after the completion of the virtual memory paging file can not contain debris, read and write faster. Or PE / emergency boot disk into the system, delete the page file, organize the disk, you can restart.
To WIN7, for example, "computer" right, property, advanced system settings, performance> Settings ..., Advanced, Virtual Memory> Change ..., automatic management canceled, custom size, set, OK, exit restart.
3. Compressed C: Windowswinsxs folder
This folder is the installation folder, and most of the time is not, and compressed to save more than 1GB of disk space. Methods: First, read and write access permissions WINSXS folder (the default administrator of this folder only read permissions), right click and select WINSXS, General -> Advanced ...--> Compress contents to save disk space. Compression process takes 10-30 minutes, depending on the hard disk performance may be.
Set by these three steps, your system should only 6G pure Win7 about the.
