FolderSizes

Overview

FolderSizes is a Windows storage analyzer for home users and organizations that need to examine disk use, including across network locations. Its strongest case is ongoing oversight: visual analysis is paired with scheduled reporting and trend tracking, while licensing ranges from a home-only edition to organization-wide coverage.

Key features

Four visualizations—treemap, sunburst, bar, and pie—let users inspect storage from different angles, and file-type breakdowns help identify what is consuming space. Searches can be narrowed by age, name, attributes, size, owner, date, and depth-related criteria. That makes the software useful for targeted investigation as well as a high-level view, though the range will matter most to people who regularly analyze large or varied storage collections.

FolderSizes scans local and external drives, mapped network drives, UNC paths, and network shares. Reports export to Excel, PDF, HTML, CSV, and XML; recurring scans can deliver automated email reports. Snapshots and trend analysis track disk usage and folder sizes over time, a meaningful advantage for teams monitoring change rather than troubleshooting a single space problem.

The free edition has no time limit and includes four visualizations, reports, advanced search, and scan filtering. The free trial has no feature limitations, so users can evaluate the full feature set before buying. Pro upgrades include priority technical support and free minor version upgrades.

Pricing

All published paid licenses are one-time purchases rather than recurring subscriptions. The Personal Edition license costs $30, paid once and covers personal and home-network use on up to two personal computers. It is the least expensive paid option, but is unavailable to organizations and comes with lower-priority support.

The Single-User Pro license costs $60, paid once for one user and is suitable for servers, workstations, and company networks. For multiple individual users, the 5 Pack costs $210, paid once and the 10 Pack costs $360, paid once; both are perpetual licenses, with the five-pack described as a 30% discount and the ten-pack as a 40% discount.

For broader deployments, the Site-Wide Pro license costs $700, paid once for unlimited users and installations within a single location or city. The Country-Wide Pro license costs $2,200, paid once for unlimited users and installations within the purchaser's country of origin. The Enterprise-Wide Pro license has custom pricing and covers unlimited users and installations globally within one organization.

Consultants have separate options: the Single-Consultant Pro license costs $499, paid once for one consultant using the software on up to five concurrent customer computers. The Multi-Consultant Pro license costs $1,399, paid once for up to five consultants and 15 concurrent customer computers. The free edition is a practical starting point for personal or preliminary use, but organizations should choose a license whose scope explicitly covers their deployment.

Platforms

FolderSizes is available for Windows. Its scan scope includes local and external drives as well as mapped network drives, UNC paths, and network shares.

Who it's for

FolderSizes suits Windows home users who want a persistent free option, and IT teams or administrators who need to investigate storage across network locations, produce reports, or track usage over time. Consultants can select licenses sized to their customer-computer workload. It is a poor fit for people seeking a non-Windows tool, and the Personal Edition is not an organizational license.

Pros and cons

• Pros: The no-time-limit free edition includes visualizations, reports, advanced search, and scan filtering, making it useful beyond a short evaluation period.
• Pros: Network scanning, scheduled email reports, snapshots, and trend analysis support recurring storage oversight across more than one local drive.
• Pros: Perpetual licenses scale from one user to global organizational use, with distinct consultant plans for customer systems.
• Cons: Windows is the only supported platform, limiting its usefulness for mixed-platform environments.
• Cons: The cheapest paid license is restricted to personal and home-network use, so organizations need a Pro license even for a small deployment.

Verdict

Look elsewhere if you need another platform or if a personal-use license is the only paid tier that fits your budget but you need organizational rights.
