SizeTrend

SizeTrend is a Windows utility for finding and reviewing storage use across files, folders, and applications. It suits people who want detailed local analysis without a subscription, while Professional is better for recurring scans, network folders, or report exports. The free edition is useful for occasional cleanup, but its comparison limit makes it less suited to tracking changes over time.

Overview

SizeTrend combines disk-use breakdowns with tools for investigating and managing files. It can show application sizes and file types, search by name, text, binary content, type, size, or date, and find duplicates by name, size, or content. It can also compress files or folders in place. That breadth is useful when a basic folder-size view is not enough; duplicate detection and compression help with cleanup, but they do not determine which files are safe to remove.

Both editions save scan snapshots. Free allows one “What Changed” comparison when a compatible snapshot exists, which is enough for a limited before-and-after check but restrictive for ongoing comparisons. Professional removes that limit and adds automatic storage history.

Key features

• Local analysis: Free scans local drives and folders, analyzes files and content, identifies duplicates, and provides cleanup and storage recommendations. It is a capable starting point for occasional disk maintenance.
• Flexible investigation: Searches by content, type, size, or date can help narrow a large scan when file names alone are unhelpful. Duplicate matching by name, size, or content gives more than one way to find repeated files.
• Cleanup tools: SizeTrend can compress files or folders in place. This offers a way to manage storage without deleting items, though users still need to decide what should be kept.
• Reporting and repeat scans: Professional exports HTML reports and scan data to Excel or CSV, and supports one-time, daily, weekly, or monthly scheduled scans through Windows Task Scheduler. These options make it more useful for regular reviews and reporting than the free edition.
• Network coverage: Professional can scan network folders, extending its use beyond local storage. Logged-off scheduled tasks cannot access EFS-encrypted files, an important constraint for users relying on encrypted files during unattended scans.
• Portable option: A single-file portable download is available, so installation is not the only way to run SizeTrend.

Pricing

SizeTrend Free costs nothing. It includes local drive and folder scans, cleanup and storage recommendations, file, content, and duplicate-file analysis, and saved snapshots. Its one-comparison allowance is the main constraint for users who want to track changes across multiple scans.

SizeTrend Professional costs $69.99, paid once as a one-time purchase, with no subscription and all future versions included. It adds scheduled scans, network-folder scans, HTML, Excel, and CSV exports, unlimited saved-snapshot comparisons, and automatic storage history. The 14-day trial exposes Professional features before purchase. This is the better fit for regular reporting or broader scan coverage; occasional local analysis does not require upgrading.

Volume pricing is per order and requires a minimum number of licenses: $49.99, paid once for 5+ licenses, $39.99, paid once for 10+ licenses, $29.99, paid once for 20+ licenses, and $19.99, paid once for 40+ licenses. An unlimited single-site license costs $999.99, paid once. These options suit organizations buying for multiple users or broad single-site coverage; purchases are processed by FastSpring.

Platforms

SizeTrend supports Windows 10 and Windows 11. The portable single-file download may suit users who prefer not to install a conventional application, but the software is limited to Windows.

Who it's for

SizeTrend is a sound choice for Windows users who want more than a simple directory-size view, especially those who value content searches, duplicate matching, and local cleanup recommendations at no cost. Professional is aimed at people who need repeatable scheduled scans, network-folder coverage, exports, or a continuing history of storage changes. It is a weaker fit for users who need logged-off scans to include EFS-encrypted files, or who need a non-Windows tool.

Pros and cons

• Pro: The free edition includes local scans, file and content analysis, duplicate detection, recommendations, and saved snapshots, making it useful without a purchase.
• Pro: Professional combines scheduling, network scans, exports, and unlimited comparisons in a one-time license that includes future versions.
• Pro: Search filters and multiple duplicate-matching methods support more targeted cleanup than size-only review.
• Con: Free permits only one “What Changed” comparison, limiting repeated change tracking.
• Con: Logged-off scheduled scans cannot access EFS-encrypted files, which can leave encrypted data outside unattended reports.
• Con: It supports Windows 10 and 11 only, so users on other platforms need another tool.

Verdict

Choose SizeTrend if you want detailed Windows disk analysis at no cost and can work within one free comparison. Its Professional license is compelling for users who need scheduled or network scans, exports, and ongoing storage history without a subscription. Look elsewhere if you need another platform or depend on logged-off scheduled scans that can read EFS-encrypted files.
