Archive contents comparer
Compare archive entry paths and content hashes.
How to use Archive contents comparer
The Archive contents comparer takes exactly two ZIP archives and lists every file path found in either, marked as identical, changed, only left or only right. It decompresses each entry and compares SHA-256 hashes of the contents, so a file counts as changed whenever its bytes differ. Folder entries are skipped, and each entry checksum is validated while reading.

Frequently asked questions
How do I compare two ZIP files?
Upload exactly two ZIP archives. The first is treated as left and the second as right. The result table lists each path with one of four states: identical, changed, only left or only right.
Does the comparer check file contents or just names and dates?
It checks contents. Each entry is decompressed and hashed with SHA-256, and files at the same path are compared by hash. A file with a new timestamp but identical bytes is still reported as identical.
Does it detect a file that was moved to a different folder?
Not as a move. Paths are compared exactly, so a moved file appears once as only left at its old path and once as only right at its new path, even if the contents match.
