Editors' reviewThis application finds files with the CHK file extension and reverts them to their original extension, but it performed poorly in our tests. Most users probably won't have any problem in figuring Flobo CHK Identifier's neat, straightforward interface. Scandisk creates CHK files from orphan file chains it finds. This application attempts to discover the original extension for each CHK file. You can browse by directory of drive to discover CHK files. Discovered files are listed where you have the option of deleting them. However, it often crashed when scanning our test drives. The demo doesn't offer the renaming feature, but limits you to deleting found corrupted files. With the many crashes we encountered and our inability to test CHK Identifier's renaming function, we can't recommend it for any level user.
One of the problems running scandisk is that if it finds FAT chains or MFT records without any corresponding files, it creates its own set of files, typically in the format File0001.chk file0002.chk etc in the folder named FOUND. When there are only a few files it is possible to guess what they are and rename the extension accordingly, however when there are several hundred or thousands of these files the task becomes a nightmare.
