Have you ever stared at your hard drive, wondering where 200 gigabytes of "system stuff" vanished to? You are not alone. FolderSizes is not merely a utility – it is a perpetual observatory for your digital terrain. Think of it as a cartographic expedition across your storage landscape, revealing hidden valleys of temporary files, towering peaks of bloated cache, and the quiet plains of rarely accessed archives.
Unlike conventional disk analyzers that give you a lifeless bar chart, FolderSizes renders your storage in a living, breathing interactive treemap and a sunburst diagram that you can rotate, zoom, and interrogate. It empowers you to reclaim space not by guesswork, but by unambiguous visual evidence.
This single macro grants you the full FolderSizes product key patch – a permanent license to operate the storage observatory without time constraints or feature limitations. No trials, no nag screens, no artificial ceilings.
Below is a high-level flowchart illustrating how FolderSizes ingests, analyzes, and visualizes your disk data. Think of it as the nervous system of your storage consciousness.

To tailor FolderSizes for your specific scanning preferences, create a configuration profile (foldersizes.profile) in the installation directory. Below is an example profile template that balances performance with depth.
[Profile]
Name = DeepScout
ExcludePatterns = *.thumbcache, *.dmp, C:\Windows\Temp
MinFileSize = 1048576 ; ignore files under 1 MB
MaxDepth = 15 ; dive 15 levels into subfolders
ReportFormat = treemap+sunburst+tabular
AutoExport = true
ExportPath = C:\Reports\FolderSizes
IncludeSystemHidden = false
NetworkTimeout = 30 ; seconds
EmailAlertOnCompletion = admin@localdomain.com
Apply this profile by placing it in the profiles subdirectory and selecting it from the dashboard's dropdown menu.
Automate your disk analysis from the command line. Below is a sample invocation for a nightly sweep of the D:\Projects directory.
FolderSizes.CLI.exe --target "D:\Projects" --profile DeepScout --output "D:\Reports\daily_scan.csv" --quiet --export-pdfThis command:
- Targets the
D:\Projectsfolder recursively. - Applies the
DeepScoutprofile (excluding temp files and dump files). - Generates a CSV report and a PDF summary.
- Runs in quiet mode (no GUI popup).

FolderSizes can optionally connect to OpenAI or Claude API to provide intelligent recommendations based on your scanning data:
- OpenAI Insight – After a scan, the app sends a condensed summary to GPT-4o, which returns suggestions like “You can safely delete 12 GB of old logs from
C:\Windows\Logsolder than 90 days.” - Claude Summaries – For enterprise users, FolderSizes sends anonymized folder structures to Claude 3.5 Sonnet, generating a plain-English report: “Your
Downloadsfolder has 48% duplicates; consider deduplication.”
Integration is optional – toggle it in Settings > AI Connectors > API Key Entry.
