Hi, Sorry, I have not understood correclty. >> when you need to stop you use the AddNewName event I cannot find AddNewName event. If your reference is to OnSetAddName then that is triggered before actual compression start (correct me if I am wrong). >> add the name to a list of files yet to be done Are you refering to Zipmaster's internal list ? >> rename the file to empty string which will cause the file to be skipped Will I have to rename the file on Hard disk or a Zipmaster variable ? >> 2. to restart you use... I will not be restarting compression.
