Installation Notes
The FolderSizes installer requires administrative privileges to properly install all components. After installation, FolderSizes can be run with standard user permissions for most operations, though administrative rights may be needed to scan certain protected system folders.
During installation, you'll have the option to integrate FolderSizes with Windows Explorer, enabling right-click context menu access to disk space analysis features directly from your file browser. IT administrators deploying to many machines can use the silent installation switches to install and license unattended.
What's in the Download
One installer covers both editions. The free edition has no time limit and includes folder size reports, treemap, sunburst, bar and pie charts, thirteen file reports (largest, oldest, duplicate, temporary, and more), multi-criteria search, and scan filtering. Entering a Pro license key unlocks report export, scheduling with email delivery, trend analysis, file system snapshots, and the command-line interface.
