Release the C disk space and find out the real culprit occupying the C disk space

Release C disk space, C disk space is too small, there is not enough space

Install a friend, I will help him install the system when the new computer comes home. When partitioning the system disk, the original I think that after an XP system is installed, it will occupy less than 2G, and it is enough to give it a 4G. I did not expect to use it for a while, he rushed to me, the taskbar always prompted the system disk space is insufficient!

After the horse arrived, I found that the system disk C disk really has less space. Look at the C drive, found that the friend did not install too much software to the C drive and did not store too many files, after using the disk cleaning tool to clean up, the remaining space of the C drive is only about 400M, a Win XP 1G, plus The friend installed a little software and stored files will be less than 3G, then where is the other 1G space?

The murderer is now:

Select all the files under the C drive, view it The size is also only 2G size. Remove the "Hide Protected Operating System Files (Recommended)" option in the View of Folder Options and select "Show All Files and Folders" in the "Hide and Folders" option. Finally found the problem, found in the root directory of the C drive hiberfil.sys and pagefile.sys these two files are surprisingly large, look at the size, found that the two files actually have more than 700 M! It seems that they are engaged in ghosts .

Kill the murderer:

Let's take a look at the hiberfil.sys file, check its size, and find the strange phenomenon, its size is exactly 256M, how and the size of the memory The same size? Coincidence? This is too clever, of course not, I found that as soon as the startup function of WinXP is started, the file will exist, and the system will save the information in the memory to the hard disk when it is sleeping. The Hiberfil.sys file is used to ensure that it can be restored to its pre-hibernation state when waking up. To be honest, the sleep function of XP is really not good, and it takes up a lot of space. If it is not compatible with the ACPI of the motherboard, it will cause the shutdown to be abnormal. It must be turned off, open "Control Panel → Power Options → Hibernate" and remove the "Enable Hibernate" option. At this time, I found that the hiberfil.sys file has disappeared under the C drive.

Let's take a look at the pagefile.sys file, which is the system page file (also known as the virtual memory file). Its size depends on how much the program is open and the minimum value of the page file you originally set. , is constantly changing, sometimes only tens of M, and sometimes more than 600M. Since this file has made the system partition tight, we will adjust it and adjust it to other free partitions (the E disk has more than 10 G unused space, put it on the E disk). 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 open virtual memory settings window, select "No paging file" will The system partition is removed; finally select the E disk. If you want to manually set the minimum maximum memory memory, select "Custom Size". If you want the system to manage it yourself, select "System Managed Partition".

Tip: After removing the page file of a partition and setting the page of a partition, you must click the "Settings" button next to it, so that your settings can take effect. Click "OK" in the window. The button is not working.

After the above settings, the hiberfil.sys and pagefile.sys files under the C drive disappeared, and the system partition space finally recovered.
