Mac Commander, a two-pane macOS file manager with a built-in document viewer

Field notes

The interface organizes a folder as a file tree beside a document viewer, with a second tree available for Commander-style copy and move operations. The page lists 16 functions, including content search, regex-based batch renaming with preview, editing and saving, a folder-aware terminal panel, and comparison of up to three documents. It identifies release 1.13.9 as a 6.2 MB free download for macOS 14.0 or later and states that automatic updates are included.
