After you have chosen your source files, destination folder, and, if desired, the folder to move unrenamable files to, this button will become enabled.
Once clicked in its enabled state, it will begin the process of opening each source file, examining it for the required data, and creating the folder structure indicated by the file's information and finally moving / copying the file to it.
It will also, if chosen, move the unrenamable files to the desired location.
This will pause the moving / copying procedure. This may be needed if you have a lot of files to move / copy and the program is using a lot of computer resources (CPU time) and you need to pause the operation to do something else.
Once the resume button is clicked, the process will resume from where it was paused. You cannot change any user options while the program is paused.
This will resume program operation after the 'Pause' button has been pressed.
This will stop the operation. You cannot resume after pressing this unless you change the user input (choose different files, change destination folder etc.).
