PartitionExplorer 1.2 is a big update: the app now runs on .NET 8, scans in the background, and adds a treemap view next to the donut chart.

Also available on the Microsoft Store, no .NET install needed.

Requirements

  • Windows 10 or 11 (x64)
  • .NET 8 Desktop Runtime (x64). Download "Desktop Runtime" under ".NET Desktop Runtime 8.0.x" if the app doesn't start.

Unzip PartitionExplorer-v1.2-win.zip and run PartitionExplorer.exe. Keep all the files in the folder together.

What's new

Views

  • Treemap: a new treemap shows each folder as a box sized by its space use, with subfolders nested one level deep. Click a box to open that folder. Switch between Donut, Treemap or Both above the chart.
  • Donut: click a slice to open that folder. Slices under 3% are merged into Other, and hovering it lists what's inside. Selecting a row in the list pulls out its slice.
  • Folders keep the same colour in the donut and the treemap.

Scanning

  • Folders are scanned in the background, so the window stays responsive. The status bar shows progress and a Cancel link.
  • Sizes are exact and go up to TB and PB.
  • Junctions and symbolic links are no longer followed, so nothing is counted twice.
  • Folders that can't be fully read show a size with * (a minimum) instead of crashing or failing silently.

File list

  • Sort by any column by clicking its header. Folders stay above files.
  • New %, Items and Modified columns.
  • Double-click or Enter opens a file with its default program.
  • Right-click menu: Open, Show in Explorer, Copy path, Delete to Recycle Bin (also the Del key) and Properties.

Navigation

  • Back and Forward buttons (also Alt+Left/Right and the mouse side buttons). Backspace or Alt+Up goes up a folder.
  • Type a path into the path box and press Enter. Environment variables such as %USERPROFILE% work.

Look and feel

  • New app icon.
  • Flat folder and file icons, Explorer-style list, Segoe UI font and a flat donut, with no black borders.
  • Window size and position, splitter, view, chart mode and last folder are remembered between runs.

Explorer integration

  • The "open in PartitionExplorer" folder right-click entry is now opt-in through a checkbox, and no longer needs admin rights.

Under the hood

  • Moved from .NET Framework 4.0 to .NET 8 (AnyCPU). The chart now uses the community WinForms.DataVisualization port.
  • Builds with dotnet build PartitionExplorer.sln -c Release.
