What is .chk?

.chk files are typically files that are created when a system scan or disk check is performed on a computer's hard drive. These files are usually created by the Windows operating system and are used to store fragments of data that have been recovered from damaged or corrupted files during the disk check process.

.chk files usually contain data that has been recovered from deleted, damaged, or corrupted files on a computer's hard drive. They are typically stored in the root directory of the drive and have names that begin with the prefix "chk" followed by a number. These files can be opened and viewed using a text editor, but they are generally of no use to most computer users and can be safely deleted. In fact, it is a good practice to clean up these files as they tend to accumulate over time and can consume valuable disk space.
