Features

• Treemap Visualizations - Draws every directory as a nested treemap sized by real disk cost and colored by kind of data, showing what fills a volume.
• Parallel Directory Scanning - Walks the filesystem with a configurable pool of worker threads and streams results, with a script to benchmark the fastest worker count.
• Trash-Based Deletions - Opens a review list of marked items, moves them to the trash or deletes them permanently after confirmation, then rescans to report space gained.
• Filesystem Scanners - Runs a multi-threaded filesystem scan that counts allocated blocks, tallies hardlinked inodes once and stops at mount boundaries.
• Protected Path Deletion Guards - Refuses to remove the filesystem root, home, mount points, system trees and paths outside the scan root, never invoking a shell.
• Disk Cleanup Tools - Lets users mark files and folders, review them, then move them to the trash or delete them while tracking the space reclaimed.
• Disk Usage Analyzers - Counts allocated blocks the way du does, tallies each hardlinked inode once, skips symlinks and stops at nested mount boundaries.
• Disk Space Analysis - Marks space that could be reclaimed with hatching on the treemap so large removable areas stand out.
• Remote Helper Binary Deployments - Uploads a checksum-verified read-only scanner helper to remote hosts over SSH without sudo and streams its results back to the local view.
• Deletion Safety Guards - Rejects the filesystem root, home, mount points, system trees and paths outside the scan root, and never passes names through a shell.
• Treemap Navigation - Supports scroll-wheel zoom toward the pointer, keyboard movement, breadcrumb sibling menus and back and forward history through directories.
• Zoom and Navigation Controls - Offers scroll-wheel zoom toward the pointer, keyboard movement, breadcrumbs and back/forward history for moving through nested directories in the treemap.
• Remote Disk Usage Scanners - Uploads a checksum-verified read-only helper over SSH without sudo and streams remote disk usage into the same treemap view.
• Block-Based Disk Usage Counting - Counts allocated blocks like du, tallies each hardlinked inode once and skips symlinks so reported sizes match actual disk consumption.
• Deletion Marking - Lets users mark files or directories for removal, absorbs nested marks and shows the projected free space before anything is deleted.
• Disk Usage Metric Switching - Switches the treemap between size, file count and last-write age, with toggles for hidden files and apparent size, recoloring tiles accordingly.
• Incremental Scan Reuse - Widen the scan from a subdirectory to the entire disk, reusing the already-measured tree so only newly reached areas are read.
• Live Scan Progress Reporting - Shows live counts of files, directories, bytes, errors and elapsed time, with a top-level overview painted before the full scan finishes.
• Reclaimable Space Scanners - Shows the volume's free space now and projected after marked items are removed, then rescans to confirm the space actually reclaimed.
• Remote Disk Scanning over SSH - Uploads a checksum-verified read-only helper over SSH without sudo and streams its disk usage results into the same treemap view.
