What is the difference between system file checker tool and chkdsk?

System File Checker (SFC) is a utility in Microsoft Windows that allows users to scan for and restore corruptions in Windows system files. It is similar to the chkdsk command, which checks for errors on the hard drive, but SFC looks specifically for system file errors. It scans the integrity of all protected system files and replaces incorrect versions with the correct versions. Chkdsk is a command-line utility tool for Windows that checks a hard drive’s file system for errors and attempts to repair any that are found. A chkdsk scan can check for physical errors on the hard drive and logical errors in the file system. Unlike SFC, it does not check for or replace corrupt files but can detect system file errors and suggest ways to repair them.

It is an important tool for keeping your computer functioning properly, as corrupted files can lead to various errors and performance issues.
