SizeTrend

SizeTrend is Windows software for examining how files, folders, and applications use disk space. Its local analysis tools show application sizes and file-type breakdowns, and can analyze file contents, identify duplicate files, and offer cleanup and storage recommendations. Searches can filter by name, text, binary content, type, size, or date; duplicate detection can compare names, sizes, or contents. The free edition includes local analysis tools and saved scan snapshots, with one What Changed comparison when a compatible snapshot exists. A portable single-file download is available, and files or folders can be compressed in place. Professional adds network-folder scanning, scheduled scans, automatic storage history, unlimited snapshot comparisons, and HTML, Excel, or CSV exports. 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 is a $69.99 one-time purchase with no subscription, and includes all future versions. Volume pricing is offered from a five-license minimum.

SizeTrend offers local disk analysis at no charge, with Professional adding scheduled scans, network-folder scanning, exports, and unlimited snapshot comparisons. Note the EFS limitation for logged-off scheduled tasks.

SizeTrend suits Windows users who want to inspect disk usage across files, folders, and applications. Professional is for users who need scheduled or network-folder scans, exports, or unlimited snapshot comparisons.
