Ver 1.4.0 Help

🚀 What's New in Version 1.4.0:

1. 📁 Windows File Explorer Context Menu:
   • Right-click any folder, drive, or folder background in Windows File Explorer and select "Analyze with DiskAnalyzer" to launch directly into target scan view.
   • Includes the official application icon in the context menu.
2. 🖼️ Crisp Executable File Icon Extraction:
   • Native Win32 ExtractIconEx P/Invoke loads authentic high-resolution application icons for .exe and .dll binaries in the scan results DataGrid.
3. 🎨 3 Top-Level Command Palette Shortcuts:
   • Dedicated Command Palette entries for (Command Palette View), (Standalone App), and (PowerToys Run).
   • Interactive in-palette subfolder navigation with an "Up one level" return item.
4. 📊 Interactive Visual Chart & "Other Items" Summary Bar:
   • Displays the Top 15 Largest Items with color-coded bars, while aggregating remaining items into a clean "Other (N items)" summary bar.
   • Tap/click any bar directly to drill down into subfolders or reveal files in Explorer.
5. 💾 Admin-Resilient CSV Export:
   • Dynamic Export CSV button state and native comdlg32.dll (GetSaveFileName) save dialog fallback to guarantee CSV export works 100% reliably under Administrator UAC integrity boundaries.
6. ⚡ Name Column Auto-Width & Real-Time Live Filter:
   • Default 350px minimum width for the DataGrid Name column so file names are never truncated.
   • Instant live search filtering as you type (keywords, *.mp4, *.exe, *.zip).

📈 Real Benchmark Results (v1.4.0 vs v1.3.7):

• O(1) Extension Category Mapping:
  • 87.0% performance improvement (reduction in overhead).
  • Replaces linear list searches (Array.Contains) with a static dictionary lookup (TryGetValue).
• Capped Degree of Parallelism (DOP):
  • 6.8% faster scanning speed on local SSDs compared to unthrottled thread execution (resolving core/lock contention and disk thread thrashing).
• Resource Efficiency:
  • 50% reduced CPU utilization (by limiting concurrent scanning workers to half of your device's core count).
  • ~30% reduced RAM allocation footprint (fewer concurrent parallel task contexts allocating memory buffers).

Thank you for all the feedback and support! Let me know what features you'd like to see next in v1.5.0!

Hey everyone! Thanks to some great feedback, I just pushed a major update (v1.3.1) to the ValleySoft Disk Analyzer!

Here is what's new in this release:

⚡ Extreme Performance Optimizations We radically overhauled the scanning engine. SSD scanning speeds are now significantly faster, and we've completely eliminated the UI hangs and freezes that could happen when scanning massive drives.

🔥 Live UI Streaming You no longer have to wait for a scan to completely finish before seeing results! The UI now populates incrementally in real-time, showing you folders and sizes exactly as they are discovered.

🛡️ Always Run as Administrator Added a new built-in "Always Run as Administrator" toggle in the File menu! It automatically saves your preference and natively relaunches the app via UAC so you can deep-scan protected system directories and hidden files without restrictions.

🛠️ Command Palette Fixes Fixed critical COM bugs and duplicate entries in the native Command Palette Extension. Also, the Standalone App and Command Palette extension are now perfectly unified into a single 1-click installation!

You can grab the update right now: 📥 Microsoft Store: Search for "ValleySoft Disk Analyzer" 📥 GitHub Releases: https://github.com/valley-soft/powertoys-diskanalyzer/releases/tag/v1.3.1

Let me know what you think of the new speeds! Your feedback has been amazing!

Easily toggle Admin rights right from the File menu to scan your entire drive.

A few weeks ago, I shared a native Command Palette extension that I built to analyze disk space right from your keyboard.

The reception from this community was amazing, but a lot of you asked for a full dedicated window to better visualize the data with charts.

So, I’ve just released Version 1.3.0! I unified the Command Palette extension with a brand new, fully-featured Standalone WinUI 3 App—all combined into one single Microsoft Store package!

What's new:

• 🎨 Beautiful Standalone UI: Launch it directly from your Start Menu to view your disk usage in a modern, dark-mode optimized window.
• 📊 Visual Bar Charts: Instantly visualize your storage breakdown to see exactly which files and folders are taking up the most space.
• 📂 Drill-down Navigation: Double-click any folder in the grid to instantly dive deeper, or double-click a file to reveal it directly in Windows Explorer.
• 📦 Unified Installation: One single install now gives you BOTH the native Windows Command Palette extension and the Standalone Desktop App.
• 🤝 Official Extension Gallery: I've officially submitted the extension to the built-in Microsoft Command Palette Gallery (currently awaiting PR approval), so soon you'll be able to install it in one click!

Instantly visualize your storage breakdown to see exactly which files and folders are taking up the most space.

The brand new Standalone UI! View all your drives and instantly drill down into heavy folders.

Double-click any folder to dive deeper, or click a file to instantly reveal it in File Explorer.

Filter your view, show empty folders, and customize your layout right from the View menu.

The brand new Standalone UI! View all your drives and instantly drill down into heavy folders.

Where to get it: The app is currently in the certification process for the Microsoft Store and should be officially live very soon! In the meantime, you can grab the new unified .msix installer directly from the GitHub releases page:

I'd absolutely love to hear your feedback on the new standalone UI and the visual charts! Let me know what features you want to see next.

Hey r/PowerToys!

I just released a massive update (v1.2.0) to DiskAnalyzer, a disk usage plugin for PowerToys.

This update practically turns it into a 3-in-1 package. Whether you like living entirely in your keyboard launcher or prefer a full visual explorer, this update covers it all.

🚀 What's new in v1.2.0

✅ Native Windows Command Palette extension — No keyword needed! Just open the new Windows Command Palette, and results will stream in asynchronously while it scans your drives in the background.

✅ Standalone GUI window — A full WPF disk analyzer you can launch instantly by typing ds gui. Expand drives, drill down into folders, sort by size/allocated/items, and reveal files in Explorer with a double-click.

✅ PowerToys Run plugin — Still here, still blazing fast, and now packed with even more commands.

⌨️ PowerToys Run Commands (Trigger: ds)

• ds drives — List all drives with used / free / total + a visual usage bar
• ds C:\SomeFolder — Browse subfolders ranked by largest size
• ds top C:\ — Show top-level subfolders ranked by total size
• ds largest C:\ — Recursively hunt down the absolute biggest files
• ds ext C:\ .mp4 — Find the largest files of a specific extension
• ds empty C:\ — Locate empty folders
• ds gui — Launch the full standalone graphical window

(Pro-tip: You can right-click any result to open it in Explorer, copy the path/size, or drill down further!)

🖼️ Screenshots

• PowerToys Run — main menu with ds keyword
• Advanced commands: largest, top, ext, empty
• ds top C:\ — top folders ranked by size
• Folder scan — C:\WINDOWS subfolders by size
• Command Palette — ValleySoft Disk Analyzer with drives

Hope this saves you some disk hunting! 🚀

Hey everyone!

I love tools like TreeSize and SpaceSniffer for finding huge files taking up space, but I hated having to open a separate app just to check my drive storage.

So, I built an open-source PowerToys Run plugin called DiskAnalyzer! It lets you instantly scan any drive or folder and see exactly what is taking up your storage—directly from your Alt+Space search bar.

Features:

• Type ds drives to see all your drives with visual usage bars.
• Type ds C:\ to instantly scan and sort subfolders by size.
• Type ds largest C:\ to recursively find the absolute biggest files burying your storage.
• Full Context Menu: Right-click to open in Explorer, copy paths, or instantly drill down deeper into folders.

I just released v1.1.0, which adds "Allocated on Disk" sizes, parallel scanning for crazy fast speeds, and full .NET 10 support so it works perfectly with the newest PowerToys updates. (It even got a shoutout in the official PowerToys release notes!)

You can grab the download and see it in action here: https://github.com/thetsaw/PowerToys.Plugin

Would love to hear any feedback or feature requests from the community!
