Thanks so much. I assumed /Y would work with the delete command as well, but it doesn't seem to actually delete the file when I use it. Should I be doing something else?
try{
var BAT = new File(Folder.temp + "/MoveFilesToArchive.bat");
BAT.open("w");
BAT.writeln('Copy /Y "E:\\Temp only\\Image Sizing Tests\\Processing Folder\\*.*" "E:\\Temp only\\Image Sizing Tests\\Archive Folder\\*.*"');
BAT.writeln('Del /Y "E:\\Temp only\\Image Sizing Tests\\Processing Folder\\*.*"');
BAT.close();
BAT.execute(); // execute the temp bat file
}catch(e){
alert("Bat MoveFilesToArchive failed to execute.");
};
