Folder Size vs SizeTrend

Folder Size analyzes Windows storage to identify large files and folders and display disk usage in bar and pie charts. It scans local and external drives, USB and flash drives, SD cards, NAS, SAN, and network shares. A File Explorer right-click menu can start a scan of a folder and its subfolders. Results include lists such as largest, oldest, newest, empty, and longest-path items, with export to Excel, CSV, or XML. The application also lets users cut, copy, paste, delete, and move files or folders. Scan data can be saved and loaded later to compare results over time. The maker says scans run locally and data such as file names and folder sizes are not uploaded. A free plan is available. Personal costs 24.95 USD as a one-time fee for a license that never expires; Professional costs 39.95 USD as a one-time fee and adds command-line automation. The listed requirements include Windows 11, 10, 8.1, 8, 7, or Windows Server 2008 or newer, at least 1 GB RAM, and 10 MB of disk space. Folder Size cannot scan symbolic links.

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.
