Hello Alistair, I don't think that the call of "zipmaster.add" is necessary. In the = example of the help (topic: TZipMaster.CopyZippedFiles) the command is only necessary to = create the destinationfile. The function "CopyZippedFiles" works fine: the files of the Sourcefile = are properly copied to the destinationfile without any extracting and re-zipping. But after the execution, I get an errormessage when I try to delete the sourcefile, because the sourcefile is still opened by the process. Thanks for your quick response regards Peter =20 -----Urspr=FCngliche Nachricht----- Von: Alistair George [mailto:bigal@xxxxxxxxxx] Gesendet: Montag, 25.
