missing xx bytes in zipfile

I am uploading some zip files with WinSCP to a remote server and I am getting this sort of message all the time.

Funny thing is, if I upload them with FileZilla, I have no suc problem. Does anyone have any idea why that might happen?

here's what it says

# unzip files.zip
Archive: files.zip
error [files.zip]: missing 51 bytes in zipfile
(attempting to process anyway)
error [files.zip]: start of central directory not found;
zipfile corrupt.
(please check that you have transferred or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)

# unzip files.zip
Archive: files.zip
error [files.zip]: missing 47 bytes in zipfile
(attempting to process anyway)
error [files.zip]: start of central directory not found;
zipfile corrupt.
(please check that you have transferred or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)

# unzip files2.zip
Archive: files2.zip
error [files2.zip]: missing 42 bytes in zipfile
(attempting to process anyway)
error [files2.zip]: start of central directory not found;
zipfile corrupt.
(please check that you have transferred or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)

You may have used text/ascii mode transfer, haven't you?

thanks -- i forgot to use 'binary'
