Select Create Signature Option. Click on Config .

Now browse the desired Directory from Directory list management, in my case I am selecting h: Drive which specifies Pen drive. Click on Add to list Option to include the directory. Click OK.

Now in start folder option, it will show us the selected Drive i.e. H: Drive. Click on the Start Option.

It will ask for the File Name, enter the File Name & click on Save. So signature for data drive will be created.

Now does some modification in data drive and repeat the same steps to create another signature after modifications in data drive.

Now click on Compare Signature Option.

Browse both files in Old Signature as well as in New Signature Option.
