FolderManifest is a privacy-first desktop software for Windows that helps individuals and organizations verify, document, and audit large folders without sending any data to the cloud. It automatically scans a selected directory, identifies duplicate files using checksum comparison, detects changes across folder versions, and generates a clean HTML manifest report that can be shared, archived, or used for compliance and audit workflows. Unlike traditional duplicate finders or cloud-based file management tools, FolderManifest is built for professionals who manage large, sensitive, or mission-critical file libraries—such as researchers, project managers, studios, engineering teams, compliance teams, digital archivists, and IT administrators. Because the entire process runs locally and offline, no file content or metadata ever leaves the user’s machine, ensuring complete privacy and control. FolderManifest addresses common challenges users face when dealing with complex folder structures: manually tracking duplicates, cleaning disorganized assets, preparing datasets for handover, validating backup integrity, or reconstructing a clear audit trail after months—or years—of file changes. With checksum-based verification, FolderManifest detects duplicate or modified files even if they have different names or timestamps, making it especially valuable for environments that rely on reliable version control and data accuracy. The software produces export-ready HTML manifest reports that include folder trees, file metadata, counts, sizes, modification details, and integrity validation results. These reports are frequently used for research reproducibility, client delivery documentation, compliance audits, data migrations, archival preservation, and collaborative team review. Every license is a one-time, lifetime purchase with unlimited scans, unlimited reports, and unlimited verification runs—no subscriptions and no recurring fees. FolderManifest supports up to 10 devices depending on license tier, making it suitable for individuals, households, studios, and distributed teams managing shared assets. Whether you’re preparing an archive for long-term storage, cleaning up years of project files, verifying that backups are accurate, or organizing a massive media or research dataset, FolderManifest provides a fast, secure, and fully offline solution to bring clarity, confidence, and audit-ready structure to your file system.
