compare files reading offset chuncks

2 posts in this topic

Hey everyone!

i writting this script to compare two files and check them for SIMILARITY (%)

; find similar files/ offsets
$offset=0xffaf
$size=32

$hFile = FileOpen("c:\image-1.jpg", 16) ; open in binary read mode
FileSetPos ( $hfile, $offset, 0 )
$f1 = FileRead( $hfile, $size)
FileClose($hFile)

$hFile = FileOpen("image-2.jpg", 16)
FileSetPos ( $hfile, $offset, 0 )
$f2 = FileRead( $hfile, $size)
FileClose($hFile)

$test = $f1 & @CR & $f2
MsgBox(0, "Char read:", $test)

the idea is to get random chunks of BOTH files at the SAME OFFSET.

it works... it shows the reading comparison in the msgbox.

as a newbie, I'd like some suggestions to make this code work properly in order to get two files (mp3 or jpg) compared and get the DIFF among them..

ex.: "file1 is 70% similar to file2" or something like that...

thanks
