Got that working now thanks but I have moved on a step. I am running all this in windows pe 3.0, the HTA file and storage. When I try to run the create or append a new wim option I follow it and it says that the image has been created or appended but when I look into it a bit further or refresh the HTA there is nothing else added either file wise or to the appended image. I ran the command manually in dos screen and it throws up an error about disk space. I have the new wim file or appending file on a 1TB USB hard drive formatted in NTFS and created via diskpart. There is 400GB left on the disk and the wim file is only about 5GB. If I do it manually with GImagex to the same USB hard drive then the image creates OK or appends OK. Any ideas ? Thanks Dicko
