This matrix describes Archi 0.5.0 on macOS with the bundled 7-Zip 26.02 engine. Supported means the operation is covered by Archi's automated compatibility corpus. Best effort means the bundled engine may handle the format, but Archi does not make a release guarantee for it yet.

Important behavior
- RAR is read-only. Archi does not create or modify RAR archives.
- GZIP, XZ, and Zstandard streams accept exactly one regular file. Use a TAR format for folders or multiple items.
- Modification is available only for single-volume ZIP and 7z archives.
- ZIP comments are supported; 7z and multi-volume comments are not exposed.
- Compound archives and single compressed streams may initially appear as one logical inner file, such as
archive.tar. Extract that file and open it separately. - Content detection uses signature and engine probing; an incorrect extension can produce a non-blocking format warning.
- Unsupported compression or encryption methods may prevent an otherwise recognized archive from opening.
- Encrypted ZIP creation uses AES-256, which some older ZIP utilities cannot read.
