While modern users take for granted cryptographic hash functions like SHA-256, early PC enthusiasts relied on simpler checksums and cyclic redundancy checks (CRC) to verify that copied floppy disks, downloaded shareware archives, or backup tapes had not corrupted. DECHK was a lean, command-line tool that could generate and verify these checksums with minimal overhead. Version 2.1, in particular, is often cited in vintage computing forums as a "goldilocks" release: stable, feature-complete without bloat, and compatible with both 16-bit and early 32-bit environments. : Built on Lazarus, it offers a simple

to instantly repair and recover corrupted .chk files created by Windows CHKDSK into their original file formats.
While Windows creates .CHK files to prevent data loss, it doesn't give them proper names or extensions, making them unreadable. Tools like deCHK look at the internal "header" of the file to figure out if it was originally a photo, a document, or a video, allowing you to open it again with the correct application. deCHK - recover CHK-files - Techcrawler.de
