Perhaps the DOS FC (file compare) command will suffice for your application:
Compares two files or sets of files and displays the differences
between them
FC [/A] [/C] [/L] [/LBn] [/N] [/T] [/U] [/W] [/nnnn] [drive1:]
[path1]filename1 [drive2:][path2]filename2
FC /B [drive1:][path1]filename1 [drive2:][path2]filename2
/A Displays only first and last lines for each set of
differences.
/B Performs a binary comparison.
/C Disregards the case of letters.
/L Compares files as ASCII text.
/LBn Sets the maximum consecutive mismatches to the
specified number of lines.
/N Displays the line numbers on an ASCII comparison.
/T Does not expand tabs to spaces.
/U Compare files as UNICODE text files.
/W Compresses white space (tabs and spaces) for
comparison.
/nnnn Specifies the number of consecutive lines that must
match after a mismatch.
