Deleting restore points can reduce the space on the system disk. Delete the restore point: the operation is as follows: My computer-> Attribute-> Advanced system settings-> System protection->; Configuration->; Delete (or: Programs-Accessories-System Tools-Disk Cleanup-Select System Disk-OK-Select Garbage Delete-Clean System Files-Select System Disk-OK-Other Options-Clean (the second time))
Why is there less and less space on my C drive? Every time I start Windows 7, I do nothing, and even uninstall some software, only to find that the space on drive C has become larger. Is it true that drive C will get smaller and smaller with WIN7 installed? What's going on here? How to solve the disk space problem of this C disk system?
As one of the most common Windows 7 problems in 10, I won't talk about its universality here. Let's get to the point and give you the perfect solution.
However, this involves some system setup and optimization. Although there is no danger, I suggest you look carefully. At least, you should know the principles and methods, and you can recover from the past at any time. After all, some reasons why WIN7 takes up C disk space are good for everyone's system, such as application caching and so on.
Remind everyone that drive C in this article refers to the drive letter with Windows 7 installed, which is represented by drive C. If WIN7 is installed in other drives, it can also be copied.
First, in-depth analysis, improve the solution.
1, hibernation file hiberfil.sys:
This file is a hidden system file under the root directory of drive C, and the size of the hidden hiberfil.sys file is exactly the same as your own physical memory. When you put your computer into hibernation, Windows 7 will write all the memory contents to Hiberfil.sys file before shutting down the system. Then, when you turn on the computer again, the operating system uses Hiberfil.sys to put all the information back into the memory, and the computer returns to the state before it was turned off. But Windows 7 won't delete this file, but save it on the hard disk, occupying some disk space in vain. With the sleep function, you can choose not to use the sleep function, and everyone in the team will turn off the hard disk owner. Take up space and read and write hard disk frequently. Assassin's t6 1 just added four G's.
Under Windows 7, the first way to safely delete hibernation files is to run cmd.exe as an administrator to open a command line window, and then run: powercfg -h off. Note that the hiberfil.sys hidden file left on drive C can be deleted directly after it is unhidden.
2. Virtual memory page file. sys:
Windows systems (including Windows 7) set the default size of physical memory to 1.5 times as a paging swap file. If you are the size of the system management, then this volume will automatically change, and it will often get bigger and bigger. If the physical memory is less, only 5 12m or 1g, you can choose to keep this file.
If you keep this file, we suggest that you put it in another partition instead of the C disk (system disk), otherwise you still need to delete it manually when making Ghost or other backups. It is suggested that the size must be specified, that is, 1.5 times the physical memory size of Ram.
If your memory is more than 2G, we suggest that you directly turn off the virtual memory function, and you will find that your entire Windows system is "flying".
Method of setting virtual memory: Click System in Control Panel-Classic View, click Advanced System Settings on the left, click the first setting (performance), and then click Advanced. In virtual memory, click Settings. Note that you can directly remove and delete the hidden pagefile.sys file on drive C.
3. The application cache brought by the 3.Superfetch function:
In Windows 7 system, the technical features of Vista Superfetch are used. For details, please refer to the technical explanation of Windows WIN7 SuperFetch/Prefetch to teach you how to set WIN7 to start pre-reading and application pre-reading.
Cleaning method: directly put C: > >;
Question 2: Why is the memory of my computer system disk getting smaller and smaller? A lot of software will put things in the system disk, and when it is used, it will leave traces on the system disk, so that the system disk will become bigger and bigger.
I suggest you download Super Rabbit and clean it once a week.
The optimizer tries not to use it, because if it doesn't, it will delete the system files.
Super Bunny can not only delete junk files, but also clean up what is left in the registry.
The problem is that the capacity of win7 system disk is getting smaller and smaller, but other software is rarely installed. What happened? When the system is running normally, files such as patches will be downloaded, so the space will be reduced, but it will not be very detailed, unless there is any program occupying your system disk space.
1, it should be noted that the desktop is on the system disk by default, so downloading or storing files on the desktop will take up a lot of system disk space.
2. Please note that C:/Windows/Software Distribution in the system directory will touch this directory. Everything below can be deleted to make the system patch cache directory.
3. Try to use tools such as Jinshan or 360 Guardian to clean up regularly, but not too frequently.
Good luck ~
Question 4: Why is the disk space of my win7 system getting smaller and smaller? Just don't put the program in it, try it with 360, it doesn't matter where you change it, you have to delete it!
Question 5: The available space of my computer system disk suddenly becomes smaller. What should I do? Computer disk C is the default system disk, and the space is getting smaller and smaller. Are all your software installed on drive C, and there are many useless files such as system patch backup? You can download Kingsoft Guardian or Kingsoft Overlord Wukong version online, which has the function of slimming the system. You can clean up a lot of useless junk files and system patch backups through system slimming. I hope my answer is helpful to you!
Question 6: Why is my computer system disk space getting smaller and smaller? The second floor is too much trouble for me. This is very simple! ! !
30 seconds to clean up computer garbage (make your computer fly like a fly) (experts estimate)
That's right! During the installation and use of Windows, there will be a lot of junk files, including temporary files (such as *). Tmp and *. _mp), log file (*. Log), temporary help file (*. Gid), disk check file (*. Chk), temporary backup files (such as *. Old and *. Bak) and other temporary documents. Especially if IE's temporary folder "Internet Temporary Files" is not cleaned for a period of time, the cached files sometimes occupy hundreds of MB of disk space. These LJ files not only waste valuable disk space, but also make the system run at a snail's pace. I believe you can't stand this! Therefore, it is necessary to clear up the blockage of LJ files in time, keep the system slim and surf the Internet easily and smoothly! Come on, friends, let's go to cclean quickly now! ! Here are the steps. It's simple. Just two steps!
Click Start → Program → Attachment → Notepad in the lower left corner of the computer screen, copy the following text (black part), click Save As, select the desktop by path, save all files with the file name of Clear System LJ.bat, and it is finished. Remember that the suffix must be. Bat, good! Your garbage cleaner has been made successfully!
Double-click it to quickly clean up junk files in less than a minute.

Question 7: The system disk is getting smaller and smaller. How to clean it? Step 1: Double-click the computer icon on the desktop;
Step 2: In this computer interface, right-click disk C (and other non-system disks) and select "Properties" from the menu;
Step 3: In the local disk (C:) property interface, find and click "Disk Cleaning";
Step 4: The progress prompt interface of "Disk Cleaning" will appear later;
Step 5: In the disk cleaning interface of (c:), a list of files that can be deleted will be listed. At this point, don't think it's finished. If you see the "Clean System Files" button in the lower left corner, click it; Try Tencent Computer Manager's system cleaning and computer acceleration functions, which can not only improve computer performance, but also save you time. Garbage Cleaning Click Clean to automatically scan the cleanable files and display the software size of the cleanable files (Internet garbage, common software garbage, usage traces, etc.). If you can't clean it, you can choose "one-click cleaning" to help the system reduce the burden and make the system run briskly.
Question 8: What if the system disk space is getting smaller and smaller? 1. The system has turned on the hibernation function (2GB of space on drive C can be released).
The original system turns on the system sleep function by default, but in fact, few netizens in China use this function, and this function needs to occupy as much as 2GB of system disk space. If this function is turned off, these spaces will be released naturally, which will solve the problem of insufficient space on disk C to some extent.
2. Modify the virtual memory path (you can release 1-2.5G space on drive C).
The default virtual memory of the system has been stored in the root directory of drive C, and the file name is Pagefile.sys This file is probably1GB-2.5GB. The files in the virtual memory can be moved to other disk directories through a series of system settings. Thereby releasing part of the space on the C disk of the system and solving the problem of insufficient space on the C disk to some extent.
3. Redundancy of desktop/document directory files (specific personal reasons)
Due to personal reasons or habits, I am used to storing downloaded files, personal data, movies and other files on the desktop or my documents, which leads to the failure of insufficient space on the C disk of the system.
This problem can be easily solved by modifying the desktop and the default directory of my documents in the registry, and the problem of insufficient disk space in the system can also be solved to some extent.
4. What files can be deleted from drive C (drive C can release 10MB-3GB).
Browsers browse a large number of temporary files generated by various situations, such as the first temporary file, traces of system use, temporary files generated by application software use, temporary files generated after Windows update, etc. Deleting these files can free up several MB to 3GB of space.
5. How to expand the space of drive C (modify the capacity parameter of system drive C again to release the infinite size of drive C).
Here, I recommend a partition software called PQ partition wizard. With this partition software, the partition parameters of system disk C and other disks can be adjusted without losing data, which perfectly solves the problem of insufficient space of system disk C.
6. In addition to the above methods, you can uninstall the software and reinstall it on the non-system C disk. In addition, if 360 security guards have the function of moving C disk, they can also be used.
Question 9: The computer system disk is getting smaller and smaller. What should I do? The system disk is recommended to be more than 60G, and the system itself will gradually become larger.
If you don't want to repartition, you can move the virtual memory out of drive C first, but this is not a long-term solution. ...
XP, right-click on my computer-Properties-Advanced-Performance-Advanced.
Change virtual memory
Select drive C, no paging file, and click Settings.
Select another disk, and the system manages the size (it can be customized, and now it can be filled in according to the allocated size), and click Settings.
Ok, restart
