4Pane is a four pane detailed-list file manager for Linux. It is designed to be fully-featured without bloat, and aims for speed rather than visual effects. In addition to standard file manager things, it offers multiple undo and redo of most operations (including deletions), archive management including 'virtual browsing' inside archives, multiple renaming/duplication of files, a terminal emulator, and user-defined tools. License: GNU General Public License v3 Changes:
When mounting a removable device partition as root, 4Pane now attempts to give the user write permission. You can now choose, when moving/pasting a relative symlink, for its original target not to be retained. i18n is now supported. There are changes to help distribution packagers. In addition to previously-supported distributions, binaries are now available for Zenwalk, Puppy, and Damn Small Linux.
