Setup renaming methods
1.Now you need to setup how the files should be renamed. This is done in the left part of the program where it says Renaming method list.
2.Click the button Add method and select a method in the appearing window. We will be using New name method in this example. With the New Name method you can construct a completely new filename based on known information of each individual file.
3.In the box called New Name you can write the new name of the file. Type in "MyFile_." (without the quotes).
4.If you look in the column called New Filename you can see the new filename each file will have. As you see will be replaced with a incrementing number starting from 1 and will be replaced with the file extension.
