Maybe an example will help file A
abef | 1938 | 4bac | 0def | 8675 file B adef | 0083 | abfd | 3356 | 2465 File A is different from file B and you want to have File A look like File B. So do the segmentation (I have chosen ' | ' as the divide between segments). After that do checksums on each segment. For each segment's checksum that differ there's a discrepancy between the two segments. So make the changes to have one segment look like the other segment. In this example the first segment's checksum would be the same whereas the checksum for segments 2, 3, 4, and 5 will be different. So modify the bits and bytes accordingly. You may want to pursue this subject further by looking into various error correction algorithms. VSmirk wrote: > Aweseme!!!
