System Knowledge Q & A: What is the huge file size of the C drive?

Q: My computer C drive has three files that are too large, plus more than a dozen G! I don't know what the problem is, please advise. The three files are: C: WindowsWinsxs, which has a huge 9GB. C: FaceProv.log, 2GB. C: Pagefile.sys, 2.4GB.

A: Let me talk about winsxs first. According to Microsoft's official instructions, the folder is meant to support the quarantine of COM and shared DLLs. Windows XP provides a folder called WinSxS<;(Windows Side-by-Side) in the Windows" directory. The system uses this folder to store various versions of Windows XP components, reducing configuration problems (DLL hell) caused by Dynamic Link Libraries (DLLs). Multiple versions of the component are stored in this folder. Windows XP allows Win32 API components and applications to use versions of Microsoft components that are identical to the version they were tested with, and are not affected by other programs or operating system upgrades. Windows XP does this through XML files that hold metadata about application configuration, such as COM classes, interfaces, and type libraries. It can be seen that the files in this folder are very important. Never delete them (there are serious problems that users can't enter the system after deleting), and C:WindowswinsxsBackup is a backup file that can be deleted.

Let's talk about faceprov.log. From its suffix name log, it is a log file that can be deleted.

Finally, Pagefile.sys, this is the page swap file, this file can not be deleted, but we can change its size and storage location: right click on "My computer /properties, then in the dialog box" Under the Advanced tab, click the “Settings button under Performance” and switch to the “Advanced tab” in the Performance Options dialog box, and then click the “Change button” under “Virtual Memory” to change the page file as needed. Size —— first select the C drive, then select “ no paging file, then click the "Set button"; then select the drive letter to generate the file, click on "Customize size" and enter the appropriate value This value is usually 1.5 times the physical memory. Click "Settings," and finally, restart the computer. The file is on another partition.
