Is it possible that your dmp file was ftp-ed from linux box to your Windows box in ascii mode? It is a binary file, so it must be transfered in binary mode....

Thanks for your reply. I know for sure that I transfer this file using binary mode.

any other suggestions???

In any case Oracle sees that dmp file as corrupted one. It was either corrupted during the transport process (which you say is not the case), or the file was corrupted during export process or the file somehow got corrupted after it was created.

Out of experience - in 99% cases it is the ascii ftp mode that is a real cause of the corruption.
