How was this file opened? uSoft C treats files opened as ASCII
in cruel and unusual ways. Expanding CR-LF and

		Treating character data ^Z as EOF

are features of 'read'ing a file opened as ASCII. Actually MS-DOS
programs in general are often guilty of ignoring directory size
entries completely.

Dump the file and look for a ^Z or open it as binary data, and
your problem has a reasonable chance of disappearing.
