It is intuitive enough that most users should get familiar with it quite easily. Getting productive with it should not take much time.

If the input folder has more than one file, they will be processed parallel. All the functionality is also available through a command-line interface.
The input is also tabbed and errors and warning as well as log messages are captured in separate tabs. A progress bar shows the overall progress. There is a percentage compression achieved indication on the interface. Should there be any problems, the log and the error/warning messages should give you enough clues about what went wrong.
