FileVerifier checks the files in the current directory if their identifying bytes are matching the expected bytes by their file extension.

   • Under User variables (or System variables if you want it available for all users), find the variable named Path and select it, then click Edit.
   • Click New and paste in the folder path where you placed the executable (e.g. C:\Tools\FileVerifier), just the folder, not the .exe file itself.
   • Click OK on all open windows to save.
