The type of app you are trying to make would be better suited to a .NET windows service I think since you need this to run on a scheduled basis and synchronize when things happen. However, I realize that might not be desireable or possible.
I have some ideas but let me get some more info. Could you maybe database which files completed successfully and which were "Bad"? If so, you could have this occur in two scheduled tasks. The first would conver the images and store their filenames in a database (or XML or WDDX) as to whether the conversion was successful. The second task could run one minute or 5 minutes later (hopefully, imagemagic will have removed its lock on the files by then) and attempt to either move or delete all files that the database says are completed or "bad". If it succeeds, it could then mark the database record for each file as complete or just delete the record. If you want, you could even put a CFTRY/CFCATCH block around the second task and do some kind of logging or something on files that are unable to be cleaned up.
