The Preferred block size section is only important if you will be creating PAR2 files. You should ensure that the settings match the way you have your UseNet newsposting software configured. If you do not use the correct values, anyone downloading your postings may find that they need an excessive amount of recover data.
The Default Priority setting determines how QuickPar cooperates with other applications running on your computer. If your computer has a single CPU, then it is probably best to set this to Idle, but if you have a dual CPU computer set it to Normal.
The File Deletion settings determine whether or not QuickPar should remove incomplete and damaged files after it completes a repair, and whether or not they should be sent to the Windows Recycle Bin.
The Verification and Repair options determine whether or not the Monitor and Repair functions should be enabled by default when verifying.
