FOLDER SIZE REPORTING

We’re excited to announce the latest version of FolderSizes, packed with significant improvements and critical bug fixes to enhance your file system analysis experience.

Key Improvements

FolderSizes v9.7 brings enhanced compatibility with official support for Windows Server 2025, ensuring seamless operation on the latest server platforms. The user interface has received substantial refinements, including improved default UI element font sizing, enhanced folder map layout with optimized aspect ratios and margins, and dynamic gradient rendering for more visually appealing displays.

Reporting capabilities have been significantly expanded. The new version introduces extended file size report default ranges, adds a ’20-60 Years’ default range to file age reporting, and greatly expands File Categories report groups. A notable new feature allows file extensions to be contained in multiple File Categories, providing more flexible and comprehensive file classification.

Our technical optimizations include improved NTFS MFT file residency test heuristics, an optimized default XSLT template for XML exports, and enhanced trend data import procedures. The toolbar icon states now more accurately reflect the current theme selection, improving overall user experience.

Bug Fixes

Our development team has meticulously addressed several critical issues that could impact system performance and user experience. We’ve fixed an incorrect snapshot node owner serialization problem, resolved rare buffer overflow scenarios during snapshot import, and eliminated snapshot generation concurrency issues.

We’ve also resolved rare unhandled exceptions that could occur when loading scan data and fixed limitations in drilling down into very large file report size ranges. These fixes ensure more stable and reliable performance across various system configurations.

Key Metric Software is proud to announce that FolderSizes v9.6 is available for download.

This new release introduces several important updates, including a wealth of performance enhancements that make common tasks faster than ever. Performance related updates include a faster regular expression filtering engine, much quicker column sorting, faster date and time calculations, snapshot data imports, and more.

We’ve enhanced the FolderSizes user interface with improved dark theme icon support, new themed dialogs, a new dark more splash screen, and much more.

FolderSizes v9.6 also introduces a core subset of product features for free, with more advanced features available via the purchase of a professional edition license.

FolderSizes v9.5.419.0 now automatically adapts its navigation and menu icons whenever the product’s dark mode theme is selected.

Dark mode icons are now rendered with light borders and dark backgrounds, improving the experience considerably. All while still scaling perfectly (with no loss of clarity) at any monitor resolution.

As per usual, the screen shot above doesn’t do this effect justice. Download the latest version of FolderSizes and see it for yourself.

Allow me to begin this blog entry with a brief story.

Shortly after the release of FolderSizes 9.0, we received an email from a customer who was mildly disappointed with our dark mode theme. He felt it was lackluster, and shared the opinion that it had been developed by people who didn’t actually use dark mode software applications.

Unfortunately, he was right. Our early attempts at implementing a dark theme were not ideal for a number of reasons. Sure, it was “less bright”, but didn’t truly embrace the look and feel of modern dark mode applications.

Well, no longer.

With the release of FolderSizes 9.5, we introduce an all-new “black” theme that permeates every aspect of the product’s user interface.

Screen shots don’t really do the new version justice, but here’s another.

And of course we didn’t just implement a new dark theme for v9.5 – there are many other improvements. It’s fact, it’s one of the largest “minor version” releases we’ve ever published.

FolderSizes 9.5 is a free upgrade for anyone that owns a v9.x license. We hope you’ll download the latest version and try it for yourself.
