What output format does the merged archive use?

ZIP, because it is the most universally readable format. The inputs can be any supported format; the output is always ZIP.

How are duplicate filenames handled?

Per the conflict toggle. Rename adds a numeric suffix (e.g. file (2).txt). Overwrite keeps only the version from the last archive containing that path.

Are folder hierarchies preserved?

Yes. Each input archive’s internal folder layout is kept intact inside the merged output.

Can I merge encrypted archives?

Not while they are encrypted. Decrypt with Unlock ZIP first, then drop the plaintext archives into Merge Archives.
