- Read the verdict, then step through the changed ranges with Previous and Next.
- Go to any offset, in decimal or hex, to read the bytes there.
Questions
Does it upload my files?
No. Both files are read in this tab in 4 MB slices, and nothing is sent anywhere.
How are differing bytes counted?
Each byte position that differs counts once, and bytes that only the longer file has count too. Differences less than 16 bytes apart are shown as one range.
Why are some ranges missing from the list?
The list keeps at most 10,000 ranges, so a very different pair stays fast. The count of differing bytes is always complete.
Do the SHA-256 values prove the files match?
The byte check already compares every byte. The hashes are there so you can match them against a published checksum.
