eDirStat vs SizeTrend

eDirStat is a cross-platform disk usage analyzer that scans files and folders and visualizes storage use. Its interactive treemap supports breadcrumb navigation and subfolder zooming, while charts group results by file type and duplicates. The directory walker distributes directory branches across CPU cores. Duplicate identification uses a seven-stage process that includes file size, partial hashes, multi-range sampling, full BLAKE3 hashing, and timestamp checks. After reviewing results, users can batch trash or permanently delete files, or replace duplicates with hardlinks. Scans can include external drives and mounted SMB/NFS shares, and directory states can be saved as compressed .edst snapshots for inspection in a browser-based WebAssembly viewer. The maker says the app runs offline without telemetry, analytics, network beacons, or crash-reporting SDKs, and that file changes require manual review and confirmation. It is open source under the MIT license. Windows, macOS, and Linux downloads are listed; the itch.io download costs 4.99 USD once and includes lifetime updates and unlimited personal and corporate devices. The Mac App Store edition requires macOS 12.0 or later and Apple M1 or later.

SizeTrend is a Windows application for examining disk use across files, folders, and applications. Its scans show application sizes and file-type breakdowns, analyze file contents, and identify duplicates. Search can filter by name, text, binary content, type, size, or date; duplicate detection compares names, sizes, or content. The free edition includes local disk analysis, saved snapshots, and one What Changed comparison when a compatible snapshot exists. A single-file portable download is available, and files or folders can be compressed in place. Professional adds network-folder scans, scheduled scans, automatic storage history, unlimited snapshot comparisons, and exports to HTML, Excel, or CSV. Scans can be scheduled once or run daily, weekly, or monthly through Windows Task Scheduler. Logged-off scheduled tasks cannot access EFS-encrypted files. SizeTrend Professional costs $69.99, paid once, with no subscription and future versions included. Volume pricing is available from five licenses, including per-license rates for larger orders and an unlimited single-site option.
