Zoomable Space Treemap

A lightweight Linux alternative to SpaceSniffer for interactive disk space
visualization. Independent open-source Linux tool, not affiliated with,
sponsored by, or endorsed by Uderzo Software.

INTERACTIVE NESTED SQUARIFIED TREEMAP
• Scans real local and mounted directories using POSIX os.scandir and
displays nested labeled folder frames wrapping colored file sub-blocks.
• Double-click any folder block to zoom smoothly into its subtree; click
the breadcrumb zoom trail or Back/Forward/Up buttons to navigate.
• Single-click or hover any block for real logical size, allocated disk
blocks, share percentage, modification timestamp, and child breakdown.

LIVE QUERY FILTER & TAG COLOR RULES
• Filter the scanned tree in real time with expressions such as *.log,
>10MB, <7d, -*.tmp, or tag:1, recomputing matching subtree totals live.
• Customize four color highlight rules (Tag 1..4) or assign manual tags
directly to files and folders, plus toggle free-space block overlay.

DRIVES PANEL, LAYOUT CONFIG & EXPORTS
• Inspect real mounted filesystems from /proc/mounts and os.statvfs,
customize nesting depth, minimum block size, and color palettes, and
export CSV breakdowns, vector SVG treemaps, or PNG snapshots.
