A client has a problem to copy a load of files from their standard FS to a new SPS : when copying folders, a few files do not copy correctly to the SPS. It seems not to be linked to file name and the client noted a tendency for the problems to happen with Excel Files (could not reproduce it). Could it be linked to a complicated directory structure? Is there any 'bandwidth saturation' problem possible for large folder copy? Is there a solution except using some tool like DocKit?
