Control changes in the choosen folder.
Choose a log file with the changes within.
It's recommended to use Java 8.
The directory is not controlled recursively, thus if files are added or deleted in other folders it is not showed. Only things in the folder choosen.
Just start a new pararell session to control another folder.
Start it with "java -jar file.jar" or with the .bat file as example. You may also start it in the background with "start javaw -jar DirecHashC.jar" .
