I have 185 CHK files on my hard drive. New ones appear every month. Most are from 2 to 50KB, but some are much larger--one being 59,392KB! They seem to be taking up a lot of space. What is the purpose of these files? I'd like to jettison all of them to create more space. Will doing so cause any problems?

CHKdsk scandisk output files
File fragments cleaned from the disk. When you run the DOS or Windows disk checking programs they can find errors and may write these out as file fragments in .CHK files. Often these can be deleted as the information is elsewhere on your hard disk. Sometimes, however, you need to recover information from a .CHK file (or files). Use UnCHK and/or FileCHK to help you do this.

Thanks for the info. Your explanation seems logical, since Scandisk always runs when my PC is recovering from a surfing crash and I save any lost data on my C: drive to play it safe; the MS Internet Explorer logo also flashes briefly when I try to open a CHK File. Do you think the excess of CHK files might have a bearing on the fact that Scandisk never finishes on my PC anymore?

I searched my hard drive and couldn't locate UnCHK or FileCHK. Please explain how I find and use this method of examining these files to make sure I'm not deleting anything I shouldn't. Thanks again for the help.

From what I remember unchk or filechk is generally done from a DOS prompt or a DOS window I don't recall which one works best so try them both. If you have so many chk files listed and scan disk isn't finishing a complete scan you may have underlying problems that need to be addressed such as bad sectors on your hard drive, corrupted files or folders in windows or ?

Since viewing the contents of those files in Windows appears to be problematic--and because my old PC really isn't performing that badly--I've decided to jettison all CHK files except the most recent (lost an icon on the desktop and can't remember what it was). Although I may lose some software that I haven't really missed, I'm curious to see if I can improve performance by freeing up all that space (60+MB) on my hard drive. Bad idea?
E.S.

as long as the chk files don't affect the operating system as a whole, you should be o.k.
