Choose a tag to compare

@ExitStatus ExitStatus released this 21 Jul 08:48

First public release of Disk Space Monitor — a borderless desktop widget that sits behind your windows and shows drive usage as a circular gauge.

Easiest — one file, no .NET install needed (self-contained)

Download the single exe for your PC and run it:

  • DiskSpaceMonitor-1.0.0-win-x64-selfcontained.exe — Intel/AMD PCs (most machines).
  • DiskSpaceMonitor-1.0.0-win-arm64-selfcontained.exe — Arm PCs (e.g. Snapdragon).

Smaller — needs the .NET 10 runtime (framework-dependent zip)

  1. Download the matching zip: ...-win-x64.zip (Intel/AMD) or ...-win-arm64.zip (Arm).
  2. Install the .NET 10 Desktop Runtime for your architecture.
  3. Unzip anywhere and run DiskSpaceMonitor.exe.

The app is unsigned, so Windows SmartScreen may warn on first run — click More info → Run anyway. To have it launch at login, enable Auto-start in the settings dialog (⚙ or right-click → Settings).

Highlights

  • Disk space widget – circular gauge per drive showing the drive letter and total size, free space, and percentage free.
  • Multiple drives – one independently placed and sized gauge per drive.
  • Always behind & click-through – pinned behind other windows, hidden from Alt-Tab/taskbar, never steals focus; hold Ctrl to interact.
  • Move & resize – Ctrl-drag to move, Ctrl-hover and drag a corner to resize; positions and sizes remembered.
  • Snapping & no overlap – snaps to other widgets and screen edges (stopping at the taskbar), stays on-screen, moves across multiple monitors, never overlaps.
  • Tabbed settings dialog – Drives, Options, Appearance, Colours; follows the system light/dark theme with a live preview that reverts on cancel.
  • Configurable refresh interval and low/critical thresholds.
  • Customisable appearance – background/overall opacity, ring thickness, and the colour of every part of the gauge.
  • Auto-start at login – optional.
  • Efficient – idle between refreshes, small memory footprint (trimmed working set + tuned GC), resilient error handling.
  • Original MIT-licensed icon and unit-tested UI-free logic.

See CHANGELOG.md for the full list.

Requirements

  • Windows 10/11
  • .NET 10 Desktop Runtime (for a framework-dependent build)
