Validate Checkfile

To check whether the directory has been compromised, it is necessary to validate the previously created Checkfile (see: Create Checkfile). This can be done as follows:

  • Select "Validate Checkfile" in the Main window.
  • You can either select the Checkfile by clicking on "..." or drag and drop the Checkfile to the text field.
  • You may also check for new files and deleted files by ticking the corresponding boxes.
  • By clicking "Validate Checkfile", the check will be started and detailed results will be displayed.
  • If MD5 File Hasher detects any changes, in the Pro Version you will be prompted whether or not to update the Checkfile. Please click "Yes", and the hash values of the changed files are automatically added to the Checkfile.


The Checkfile will normally be placed in the same folder where the files are located which have been selected. Unless the file name is changed by the user, the default file name is: "checksum.md5".
