The read and write totals count the rows of the table below, where one row can stand for a family of formats. Every app counts its own formats differently, so the totals are for orientation and the table is the comparison.

Format matrix

Read means the app can list an archive's contents and extract from it. Write means the app can produce that format — creating it, and where noted updating it. Formats neither app handles are left out.

Notes

1MacPacker identifies formats by content rather than extension, so any ZIP-based container opens as ZIP whatever it is called.
2Writing a JAR, APK, IPA or similar means writing a ZIP container: none of these apps produce the signing or manifests that make a valid platform package.
3The Unarchiver reads ARJ but not multi-part ARJ sets (vendor's own annotation: “No multi-part”).
4The Unarchiver reads only pre-2.0 ACE archives — no WinAce (vendor's annotation: “Only old files”).
5Supported in practice, but not listed on the vendor's own published format page.
6.xip is a XAR container, so MacPacker opens it as one.
7MacPacker joins split ZIP sets only — spanned (.z01…) and numeric (.zip.001…). Split RAR or 7z sets are not recognised.
8ZIP only.
9The unar and lsar tools are a separate download from the app.
