FolderSizes

FolderSizes is a Windows tool for analyzing storage on computers and network locations. It is best suited to people who need to investigate disk usage in detail or produce repeatable reports, rather than just glance at a drive’s free space. Its standout advantage is the combination of deep search and ongoing reporting; home users can start free, while organizations need a Pro license.

Overview

FolderSizes brings visual analysis, file-level search, and reporting into one storage workflow. It can scan local and external drives, mapped network drives, UNC paths, and network shares, which gives IT staff a way to examine storage beyond a single workstation. For a one-off check, that breadth may be more than a casual user needs; it matters when diagnosing space use across multiple locations or tracking changes over time.

Key features

Four visualizations—treemap, sunburst, bar, and pie—show storage distribution from different angles, and file-type breakdowns help identify what kinds of files occupy space. Search filters for age, name, attributes, size, owner, date, and depth let users narrow results to specific cleanup or investigation questions. The range is useful for focused analysis, though people seeking only a simple visual overview may not need this level of detail.

Reports export to Excel, PDF, HTML, CSV, and XML. Recurring scans can send automated email reports, while file system snapshots and trend analysis track disk usage and folder sizes over time. These tools make FolderSizes a more compelling choice for ongoing capacity monitoring than for occasional manual scans.

The free edition has no time limit and includes the four visualizations, reports, advanced search, and scan filtering. The free trial has no feature limitations, so readers can evaluate the full feature set before deciding whether a paid license is warranted. The company also states that its software is malware-, spyware-, adware-, and quality-guaranteed; Pro upgrades include priority technical support and free minor-version upgrades.

Pricing

FolderSizes uses perpetual licenses rather than recurring subscriptions. The free edition covers core analysis without a time limit, making it a practical starting point for personal use. Paid options chiefly determine who may use the software, how many computers or consultants are covered, and whether Pro support benefits apply.

• Free edition: No charge and no time limit; includes visualizations, reports, advanced search, and scan filtering. A good fit for home users who need the core analysis features.
• Personal Edition license — $30, paid once: A perpetual license for personal and home-network use on up to two personal computers. It is unavailable to organizations and has lower-priority support, so it is not the right license for workplace use.
• Single-User Pro license — $60, paid once: A perpetual license for one user, suitable for servers, workstations, and company networks. This is the direct choice for an individual professional who needs organizational use.
• Single-User Pro 5-pack — $210, paid once: A five-pack perpetual license with a 30% discount, for teams covering five users.
• Single-User Pro 10-pack — $360, paid once: A ten-pack perpetual license with a 40% discount, for broader user coverage.
• Site-Wide Pro license — $700, paid once: Unlimited users and installations within a single location or city. It fits organizations with a concentrated deployment.
• Country-Wide Pro license — $2,200, paid once: Unlimited users and installations within the purchaser’s country of origin, for wider national deployment.
• Enterprise-Wide Pro license: Custom pricing for unlimited users and installations globally within one organization.
• Single-Consultant Pro license — $499, paid once: One consultant may use the software on up to five concurrent customer computers.
• Multi-Consultant Pro license — $1,399, paid once: Up to five consultants may use the software on up to 15 concurrent customer computers.

The lower-cost Personal Edition is restricted to personal and home-network use; organizations should choose a Pro license. Pro upgrades add priority technical support and free minor-version upgrades, so the free edition and personal license trade away those support benefits.

Platforms

FolderSizes runs on Windows. Its scan scope includes external drives as well as local and network storage, but the software itself is not offered for other desktop platforms.

Who it's for

FolderSizes suits Windows users who need more than a basic disk-space view: IT staff inspecting network shares, administrators generating recurring reports, and consultants scanning customer computers all have license options aligned to those uses. Home users can get useful analysis from the no-time-limit free edition, while someone who only wants a quick, occasional check may find the search and reporting depth unnecessary.

Pros and cons

• Pro: The free edition has no time limit and includes visualizations, reports, advanced search, and scan filtering, so core analysis does not require a trial countdown.
• Pro: Network paths and shares are in scope, making it useful for storage investigations beyond a local drive.
• Pro: Multiple export formats, scheduled email reports, and trend tracking support repeatable operational work.
• Con: Windows-only availability rules it out for teams that need a cross-platform analyzer.
• Con: Organizational use is excluded from the Personal Edition, requiring a Pro purchase even when a home-oriented license might otherwise seem sufficient.

Alternatives

• TreeSize is another Windows freemium option with a free trial, making it an alternative for readers who want to compare another Windows tool before choosing.
• SizeTrend may suit Windows users who want free local analysis, including cleanup and storage recommendations.
• Disk Analyzer Pro is a freemium option on Windows and macOS; its free personal edition includes local-drive usage reports, file and folder deletion, and duplicate-file reports.
• eDirStat is a free option for readers comparing tools across Linux, macOS, web, and Windows.
• StorageRadar is a macOS alternative with a free tier that includes deep storage scanning, treemap and sunburst views, and local snapshots.
• Drive Atlas is worth a look for Linux or Windows users: its free plan covers the first two drives with all features and no card or timer.
• Disk Auditor is a free Windows alternative offered as a portable single executable, with scanning, visualization, and exports to several formats.

Verdict

Choose FolderSizes if you need Windows-based storage analysis that reaches network locations and pairs detailed filters with scheduled reports and trend tracking. Its no-time-limit free edition is a strong starting point for personal use, and perpetual Pro licenses accommodate professional and larger deployments. Look elsewhere if you need a non-Windows app or only a lightweight, occasional disk check.
