We have found that the way files are transferred differ based on the mime characteristics associated with the file's extension. It seems that many of the Windows programs look at this to determine how to handle the file I/O.
We have found that this impacts Windows to Windows transfers as well as Windows to SAMBA. We haven't had the time or resources to allocate to researching this further, but maybe this might help in some of the debugging. Sincerely, Robert F. Thomas A. S. Thomas, Inc.
