How to file integrity monitor — compare two files
- Step 1Drop two files (A and B) — Upload both files for comparison.
- Step 2Compare — Both are hashed simultaneously; if hashes differ, first-difference offset is computed.
- Step 3Review or export the report — View identical/different status, divergence offset, and hex preview.
Frequently asked questions
What if the files are huge?+
Hashes stream chunked. The first-difference detection covers the first 100 KB after divergence — sufficient for triage.
Does it work for binary files?+
Yes. The integrity monitor is byte-level — it compares any file types equally.
Can I compare PDFs semantically?+
This is a byte-level integrity check. For semantic PDF diff, use the PDF Diff tool in the PDF suite.
