Why the free space of my system disk becomes smaller and smaller? Every time when we turn on the computer, we may find our system disk becomes larger and larger , doing nothing, even with some software uninstalled. Why?
As one of the Top10 Vista problems, we've got a perfect solution for you. However, some system optimizations are included, we strongly recommend you to read carefully, although there is nothing dangerous. Yet at least you need to know how and why so that you can restore to default any time.
Now follow me, to do some operations with your scalpel. (C=System Disk)
鈪燗nlyzation and Solution
This file is hidden in the system, which is as large as your physical memory. When your computer becomes in hibernation, Windows Vista will write all the sessions in memory into the Hiberfil.sys while the next time you wake up your computer, the system will put all informations back to memory. However, this file will not be deleted, in stead, it will be kept in the harddisk, covering part of the space. What's more, this function will read your hard disk frequently. So we have turned it off as soon as we had our Vista installed because the sleep mode is good enough to use. My Acer got 2G extra space after doing this.
B.Well, how to safely remove the hiberfil.sys?
Just right-click on the Command Prompt and hit "run as administrator". Type in powercfg -h off and press enter. Now we've done it.
Attention: There may be a hiberfil.sys remained in your system disk. Just find and delete it after you hit "show all file"in folder opition.
A. What's pagefile.sys?
Windows, including Vista, set a paging file, 1.5 times as large as the physical memory to use as a virtual memory. In default, it is the system that manages it and it changes automatically, usually larger and larger. If you own a 1G or 1.5G physical memory, you need to keep it. But if you have a physical memory larger than 2G, you can choose to turn it off and you will find your system runs like flying.
B.How to remove it?
*Right-click Computer or press Win+Break
*Hit advanced system settings around the top on the left.
*Enter performance settings
*Press change in the advanced tab
*Uncheck automatically manage paging file size
*Check no page file and hit set
Attention: There may be a pagefile.sys remained in your system disk. Just find and delete it after you hit "show all file"in folder opition.
3.Applicatuion Cache Brought by Superfetch
Windows Vista brought a new technical feature named superfetch. Windows SuperFetch enables programs and files to load much faster than they would on Windows XP–based PCs.
When you're not actively using your computer, background tasks—including automatic backup programs and antivirus scans—run when they will least disturb you. These background tasks can take up system memory space that your programs had been using. On Windows XP–based PCs, this can slow progress to a crawl when you attempt to resume work.
SuperFetch monitors which applications you use the most and preloads these into your system memory so they'll be ready when you need them. Windows Vista also runs background programs, like disk defragmenting and Windows Defender, at low priority so that they can do their job but your work always comes first.
B.How to remove Application Cache Brought by Superfetch?
Delete all files in c:\windows\prefetch.
A.What's Application Cache?
When we use some applications in Vista, temporary files are produced. That's what we call application cache, located in c:\windows\temp and C:\Users\user's name\AppData\Local\Temp .
B.How to remove?
Just delete all files in c:\windows\temp and C:\Users\user's name\AppData\Local\Temp .
