I have tried to reproduce your problem. All rename methods are working without problems on my Entire Connection 4.5.1 on Windows XP SP2. On another PC with Win XP SP2, I have tried the rename with Entire Connection 4.4.1Pl6 without any problems, too.
Thanks for the quick response, it’s something strange, I’ve done some more test but rename still not working, all other tasks provided with the product or written by us works fine but at the moment I’m not able to rename the file.
Tired of checking the REN task and DOS RENAME I tried using DOS COPY and DEL task in conjunction and everything works correctly. I can’t understand why the RENAME does not work but I don’t have more time to waste on this.
