After installing Windows7 system, even if no application is installed, the C disk takes up more than 10G. In fact, there are some things that we may not need. If we can remove some things we don't need from the hard disk and do not affect the system operation, does it save a lot of space?
Let us see what way we can help save hard disk space Windows7 system. Great
1. correctly set the virtual memory
role of memory in the computer, the computer all running programs need memory, program execution if a large or a lot, it will lead to memory depleted. In order to solve this problem, Windows uses virtual memory technology, which takes out part of the hard disk space to act as memory. This part of the space is called virtual memory. The virtual memory exists on the hard disk in the form of PAGEFILE.SYS. Virtual memory is only a supplement to the lack of physical memory, so do not deify, virtual memory read and write performance (that is, hard disk read and write speed) only one-tenth of the physical memory performance, and high-frequency read and write operations on the hard disk damage Big! It is easy to appear bad sectors on the hard disk! If you don't need it, you can use it less. If you can use it less, you can use it less! The principle is enough to use + a small amount of allowance. Under
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 normal occupancy can be 256MB). 1GB memory, according to the actual memory usage, you can set the virtual memory to 128-512MB (the sum of memory + virtual memory is generally 256-512MB higher than the normal occupancy). Memory is 2G and above, you can generally disable virtual memory (software limited to a small amount of virtual memory, such as 128MB). Some people who do use a lot of memory, such as playing large 3D games, making large pictures, 3D modeling, etc., and receiving the system memory shortage warning, 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 Write faster. Or use the PE /emergency disk to boot into the system, delete the page file, defragment the disk, and restart. Take Win7 as an example, "Computer" right click, Properties, Advanced System Settings, Performance settings. .., Advanced, Virtual Memory" changes. .., automatic management cancel, custom size, set, OK, exit restart.
2. delete the hibernation file hiberfil.sys
many people often do not find out what is the computer sleep. In fact, there are two low-power operating states in the computer, sleep and sleep. The common function of our computer is the sleep function, that is, the computer enters the low-power state after a certain period of time, and the working attitude is stored in the memory, and the original working state can be restored in 1-2 seconds after the recovery. This feature is very useful and is the most commonly used. However, hibernation is to write all the memory information into the hard disk, taking 4G memory as an example, that is, to write 4G files to the hard disk, and then shut down. To restore the original working interface, you need to read the 4G file to the memory. The reading and writing of 4G files takes a lot of time, which is no less than normal booting, so the hibernation function is not practical now. The hibernate HIBERFIL.SYS file is used to save memory state during sleep. Will occupy the space equivalent to the memory capacity of the C drive (for example, 4G memory, this file is also 4G), so it can be deleted without affecting everyone's use.
methods of operation: CMD running with administrator privileges, hit the following command: POWERCFG-HOFF automatically delete the file.
(How to run an administrator: in the "All Programs" - "Run as administrator" "Command Prompt" on the right, select - "Accessories")
3. Compression C: Windowswinsxs
folder this folder is the installation folder system, most of the time is less than after the compression can save more than 1GB of disk space. Method: first obtain the read and write permissions of the WINSXS folder (the default administrator only has read access to this folder), then select WINSXS right mouse button, regular --" advanced. ..--"Compress content to save disk space. The compression process takes 10-30 minutes, depending on the performance of the hard drive.
By setting these three steps, your system should only pure Win7 about the 6G.
