Today, I suddenly found that disk C has a serious shortage of space. I went into disk C and saw two large files: hiberfil. sys and pagefile. SYS. What are the two files used for? Can I delete them?
The results of online access are as follows:
A: "hiberfil. sys is a system Sleep file, which is as large as the physical memory of the computer. It can be deleted (but cannot be deleted manually), as long as "power options" are enabled in the control panel ", then, under the "Sleep" tab in the Power Management dialog box, remove the check box before "enable sleep" and the Sleep file will be automatically deleted.

"Pagefile. sys "is a page swap file, which cannot be deleted, but we can change its size and storage location: Right-click" my computer/properties ", click the "Settings" button under "performance" under the "advanced" tab of the dialog box, and switch to the "advanced" tab in the "performance options" dialog box, click the "change" button under "Virtual Memory" to change the page file size as needed-select disk C, select "non-paging file", and click "set; then select the drive letter to generate the file, click "Custom size" below and enter a suitable value, which is usually 1.5 times the physical memory, and then click "set ", finally, restart the computer and the file will be in another partition.
