DiskScope vs SizeTrend

DiskScope is a free, open-source desktop app for analyzing disk usage, finding files, and uninstalling applications. It scans files, folders, and apps in parallel, showing results in a sortable table, tree explorer, and zoomable treemap. Views include application sizes and file-type breakdowns. Fuzzy search filters by type, extension, size, and modified date and is designed to remain smooth beyond 100,000 rows. DiskScope reports actual on-disk usage, including sparse and compressed files. Deleted items move to the Recycle Bin; emptying it permanently clears contents after confirmation. On Windows, the Applications tab shows an installed program’s command before launching its native uninstaller. Disk analysis and search work on Windows, Linux, and macOS. Downloads list Windows 10/11 x64, macOS 12 or later, and Linux x64 builds. The macOS and Linux builds are marked experimental and not tested yet. The app runs locally with no telemetry, according to its maker, and checks for signed updates.

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.
