Solution or Workaround
Why does DXFARC return 'unexpected EOF'?
This situation only occurs if the DXF file has been corrupted before being read by ARC/INFO. The message is returned if the DXF file is a binary file, and the file was transferred using FTP, PC-NFS, or some other networking software using an incorrect protocol; for example, ASCII instead of BINARY.
Make sure that the transfer protocol is BINARY.
