.CHK files:
.CHK files are created from 'lost clusters' by programs such as CHKDSK and SCANDSK. When working with open files, directory information is stored in RAM as well as on disk. Changes to files can be stored until 'quiet' moments, when they can be written to disk without interrupting the (human) work flow. If an event, such as power failure, occurs before files are closed, incomplete files remain on disk. These incomplete files are often data without directory information; thus, the data is useless, and the operating system cannot associate this 'stray' data with the corresponding file.
CHKDSK and SCANDSK simply creates files from this 'stray data' and assigns the file a name, arbitrarily FILE0000.CHK, FILE0001.CHK, until all the lost clusters are again part of files. An ambitious user could examine these files and 'RE-APPEND' them to re-create the original lost files. Sometimes, we're lucky and the entire file is one chain and only needs to be restored with its original name. Other times, the chains are short and the file is in tatters. Often it's easier to cut our losses delete the files. Each case is different. Text files lend themselves to repair while binary files seldom survive the process.
