The first thing we need to know is that Windows7 doesn't take up that much space, except to include files such as virtual memory, to ensure that the system is used more smoothly. Of course, it is recommended that you partition the C drive at 30G or higher during installation, because many friends now install the software on the C drive, and the daily use will also reduce the capacity of the C drive, so the system home small editor suggested It is better to allocate a larger space if you have the conditions. Usually we
after installing Windows7, C disk there are several main folder, is the main source of space occupied:
ProgramFiles: Applications folder, the default will be a general software here installation (64 users will be more of a ProgramFiles (X86) folder, the directory is installed in the system 32 software is normal)
ProgramData: system folder, placed in the program using the data, Settings and other files are not recommended for deletion.
Windows: The main storage operating system files in a folder, very important
users: save the user's profile and data, in Windows7 "Users" folder is actually XP, DocumentsandSettings folder.
pagefile.sys file system hibernation function occupied hard disk space::
hiberfil.sys virtual memory paging file
There are some other folder:
$ RECYCLE.BIN: system folder, which is the "Recycle Bin", can not be deleted
SystemVolumeInformation: system volume information file. This folder stores the backup information of the system restore.
PerfLogs: Windows log file information, such as ScanDisk error message. PerfLogs is automatically generated by the system.
MSOCache: Local Installation Source
Office of the above is the "C drive" in the main file and folder contents, in addition there will be a number of other documents in the course of, for example, may be There are files named after the alphanumeric characters. This may be the Windows Update update temporary folder, which is usually deleted automatically.
below detail about the Windows folder and the user folder:
Windows folder: Save the main document that the Windows system folder
this document, which occupies the largest The folders are system32 and winsxs.
System32: important system folders, file contains a large number of Windows users, mainly Dll, CPL, and some drivers support file system operation.
Winsxs: Winsxs is the Windows directory Vista /Windows7 is a very important folder, inside that folder there are many important components, versions are also very complex, in order to ensure the normal operation of Windows, which files are Cannot be deleted.
user folder:
this folder will include content data the user process, the program content as well as documents, music and other files into the user will be found to have been named after the username folder Folder, when opened, you will see the desktop, my music, my pictures, my videos, favorites, my documents, music, AppData, Downloads and other folders.
Desktop: will save all the current content on the user's desktop, many of my friends used to put files on the desktop, these are the C disk space occupied by Oh!
My Music, My Pictures, My Videos: As the name suggests, these are the default content will be stored here, of course, many of my friends are in a separate place. In addition, one thing to note is that content such as apps downloaded using itunes will be placed in my music folder by default, and will also take up space on the C drive.
Favorites: Contains IE browser favorites file
Downloads: IE as well as some downloadable content many browsers or other programs will be saved in the default here, it will also take some "C Disk" space.
My Documents: is my document, save a log file of many programs, such as the commonly used Outlook, QQ, MSN and other folders of data files are stored here.
AppData: data storage program, which is to get up early Windows systems ApplicationData, install the software in the user-defined settings, temporary folder, such as the Quick Launch folder
front
us. What are the contents of the "C drive"? Let's take a look at how to reduce the burden of the "C drive".
1. clean up temporary files: You can free up disk space by the system's own Disk Cleanup and let the computer run faster. This program deletes temporary files, emptys the recycle bin, and deletes various system files and other items that are no longer needed. You can enter "Disk Cleanup" in the Start menu search box to enter, select the partition to be cleaned, select the file type to be deleted and then OK to clean it. (Other third-party software is also included cleaning function, such as Ccleaner software, but third-party software may be some risk, please note that when used)
2. delete unwanted software: in fact, some friends will ask, I have a lot of software installed in the C drive, but why is the C drive space still less and less? In fact, although the software installation is not in the C drive, the data generated by the software, the user-used custom data, etc. are stored in the C drive, such as ProgramData, AppData, etc., these software will still occupy some space. It is recommended that you do not install too much software that is not used. It is best to delete the one-time use software after use.
3. Desktop files do not much: Although the file on the table is very convenient passage of time will develop everything tabletop habits. Although this is very convenient, but it will take up the C disk space, and some friends will even reach a few G or more. So everyone can put the files in other partitions is the best drop, of course, you can also create a folder in other partitions, then shortcut to the desktop, drag the file into it just fine. In addition, you can change the location of the desktop folder to another location, which we will introduce below.
4. location of those folders: C drive in the desktop user folder, Downloads, My Pictures /music /video folder, the default is the C drive, but you can manually change these files The position of the clip. To get the desktop: Open the C drive - user - corresponding user name folder, right click on the desktop folder icon, select the properties, click the "Location" tab, and then click Move to select the folder of the other partition to save the content, other folders You can also set up (if you use problems in the future turn, click on the "restore defaults" to restore the default settings, click the "Find target" to locate the appropriate directory) according to this method
5. Why sleep also accounted for Space: Some friends will ask, why do I take up space to sleep? First of all, let's take a look at hibernation. Hibernate actually saves the data in the memory on the hard disk and shuts down the computer. When it is turned on, it will restore the data to the memory again, which is convenient for quick startup. If the "hibernate" function of Windows is enabled, a file of the same size as the memory will be generated on the system disk, named hiberfil.sys, and this file cannot be transferred to other partitions, so the sleep function will occupy a certain C. disk space, if not, then you can turn off the command:
please start menu search box, type cmd, and then right-click cmd.exe icon and select "run as administrator" in the Enter the following command at the flashing position and click Enter to make the command take effect. Does not have the
powercfg-hoff
run to complete any tips, as shown:
Then we look at the system disk space will find more than a few The available space of G.
6. how do virtual memory: virtual memory combines RAM and temporary space on the computer's hard disk. When RAM runs slowly, virtual memory moves data from RAM into a space called a paging file. Moving data in and out of paging files frees up RAM so that the computer can get the job done. Generally speaking, the virtual memory is automatically managed by the system when the system is installed. Of course, we can adjust these manually. In order to reduce the space occupied by the C drive, we can move the paging file to other disks with larger space to save the system. disk space and reduce disk fragmentation:
(1) right-click "computer" and click "properties" in the page that opens, click on the left side of the advanced system settings in the open window, click the performance section of the "settings" button, and find the "advanced" tab
(2) click the "change" button, open the "virtual memory" window, deselect "automatically manage paging file for all drives Check the size before, then select "No paging file", click the "Settings" button to make the settings take effect, so the paging file in the system disk is deleted.
(3) Select the system disk another disk, and check "System managed size", click on "Settings" button and click "OK" to apply the settings as prompted to restart your computer. This way, the paging file is transferred to another disk.
When our C drive smaller, do not worry, look at the above methods, compared can help save up some of the space.
