Directory Backup Extension (DBE) is a highly advanced 80x25 textmode, keyboard driven file manager. It maintains and preserves unique disk IDs and file entry status flags, long filenames, jump points, and single-steps selection bar and window updating synchronously with progress of file copy, move, delete, compare, and view operations. It also maintains a global selected list and numerically ordered queue along with normal file/folder lists; all are sortable by name, ext, size, time, order read from disk, and queue number, as well as manually. The tag and target states for file operations are independent, and can be controlled and manipulated in manifold ways; and DBE can also be instantly exited without losing any of the important status information relevant to an ongoing series of file operations. Extensive, detailed documentation accompanies this program, and its internal help also displays keyboard diagrams with nearly all features shown identified with their mnemonically related keys. DBE also handles unpredictable USB drive-letter assignments under XP/2000 quite well.
