PDF3D ReportGen allows you to save a session state for conversion later if you are not ready to convert it right away. By saving a session, you do not need to specify the settings again when you are ready to convert the file. The session can be saved at any point before you do the final conversion. All settings defined until that point will be save in that session. The session will be saved as a .pdf3dsettings XML file.
State files are recommended to be saved near the location of your project and data files. The state file contains links and paths to the input, output and other related files. Where possible, i.e. on same drive, relative paths are stored in the state file relative to where it is saved. This way the state file and other project files are relocatable. Once a state file is loaded, any input files no longer available on that path are shown in red.
