The mystery of Windows operating system space loss

I used the old computer with a hard disk of 40GB. At that time, I installed Windows 98 operating system, and the system partition was 5GB. Upgraded to Windows XP not long ago, with the SP2 patch. After a period of time, the hard disk is in a hurry, and the taskbar always indicates that the system disk space is insufficient.

Right click on the system C drive and select "Properties". The remaining space is less than tens of MB. But choose all the files under the C drive, view the size, only 4GB size, and 1GB space is not known. Even more strange is that my Windows system is only about 1.7GB when it is installed, but now it is a huge monster of 2.65GB.

The mystery of space loss

Click “Start→Control Panel→Folder Options→View” to remove the “Hide Protected Operating System Files (Recommended)” option in the Advanced Settings area. And select "Show all files and folders" in the "Hide and folder" option. At this time, there are two files hiberfil.sys and pagefile.sys and one System Volume Information folder in the C drive. Each of the three Dongdong is almost 300MB. It turns out that these are a few ghosts.

Solution

Select "Control Panel → System → Advanced", click the "Settings" button in the performance area; then select "Advanced → Change", select the partition where the system is located in the "Virtual Memory" window, and select " No paging file → Settings will remove the system partition paging file; finally select other partitions (larger space). If you want to manually set the page file size, select "Custom Size"; if you want the system to manage it yourself, select "System Managed Partition". At this time, the pagefile.sys file under the C drive has been transferred to the partition of your choice.

The System Volume Information folder is used to store system restore files. For it, you can select "Start → Control Panel → System → System Restore" to turn it all off. If you do not want to disable System Restore, you can double-click "My Computer", right-click the system partition letter, select "Properties → General → Clean Disk → Other Options", click the "Clean" button in the System Restore area. At this time, you can find that the folder has changed from 300MB to 30MB.
