## What it is
muCommander is a lightweight, open-source, dual-pane file manager written in Java that runs on any OS with Java support. It offers a virtual filesystem with support for local volumes, FTP, SFTP, SMB, NFS, HTTP, cloud storage (Dropbox, Google Drive, S3, HDFS), and archive formats like ZIP, RAR, 7z, and TAR.

## Use cases
- manage files with a dual-pane file manager
- copy and move files between FTP and SFTP servers
- browse cloud storage like Dropbox and Google Drive
- extract and create ZIP, 7z, and TAR archives
- batch rename files
- use a portable file manager on any operating system
- connect to SMB and NFS network shares
- calculate file checksums

## When to choose
- you want a Norton Commander-style dual-pane file manager
- you need one file manager that works consistently across macOS, Windows, and Linux
- you frequently transfer files between local disks, remote servers, and cloud storage
- you want built-in archive handling and batch rename without extra tools

## When to avoid
- you need deep native OS integration like Finder or Explorer shell extensions
- you require a very lightweight native app without a Java runtime dependency
- you need advanced features like file indexing or media preview found in heavier managers
