Actually, Windows Scandisk or Chkdsk may convert your files to a CHK file (Filexxxx.chk) while verifying the corrupted file system. Unfortunately, Windows does not offer a tool for CHK file recovery. But don't worry! UnCHK can help you open a CHK file and recover lost files in an easy way.

UnCHK is a free tool for CHK file recovery. It can examine the contents of the CHK files and determine if the contents are known to file types such as audio files, video, images, archives, executable files, and documents. When contents are recognized (for example, as a Word document), the CHK files are copied to a new file with the correct file extension (Filexxxx.CHK -> Filexxxx.DOC). The new file extension allows you to easily open the file using the associated program. That how UnCHK works to manage CHK file recovery.

2. Why cannot I recover 2GB data for free?

It is recommended to check the version installed is Free or Trial because they are different versions.

Trial has data preview function but cannot save any files, while the Free version enables to recover 2 GB files. The default free space is 500 MB and you may share the product on social media to get another 1.5 GB.

3. Why cannot the recovered files be opened?

A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.

If the files with original file names and folder structures cannot be opened, one possible reason is the corrupted directory info. There is still a chance to recover the data content with the RAW Recovery method in our software.

4. Why isn't it suggested to recover the files back to the original drive?

The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss. So you should prepare another disk to save the files.
