About FolderSizes

FolderSizes scans local drives and network shares to show where disk space is going. It lists folder sizes, finds large, old, temporary and duplicate files, and breaks down files by type, size, attributes, age, depth or owner, with bar, pie and treemap views.

It is also aimed at administrators: reports can be scheduled and emailed, exported in several formats and run from the command line, and file system snapshots support trend analysis of disk usage over time. A free version is available, with a Pro upgrade.

  • Scheduled reports with email delivery
  • Snapshots and trend analysis of usage over time
  • Command-line support and several export formats

Limitations

  • Filelight

    Shows disk usage as concentric rings you can click into.
