A single hash proves a file is byte-for-byte identical to the trusted original, catching silent edits.
Generate a checksum manifest once, then verify the same files after every copy, sync, or restore.
Export an HTML report that auditors, clients, and release managers can open without installing anything.
A checksum verifier is a tool that computes a cryptographic hash (usually SHA-256) of a file and compares it against a known-good value to prove the file has not been altered. FolderManifest is a checksum verifier that runs locally on Windows and Linux and can verify one file, a folder, or an entire archive at once.
You can download FolderManifest for Windows or Linux and verify checksums free for 7 days. The installer ships a desktop app plus a CLI, so the same verifier works for one-off checks and scripted CI jobs. No credit card is required for the trial.
Yes. FolderManifest computes SHA-256 by default, with MD5, SHA-1, and CRC32 also available for legacy workflows. SHA-256 is the current standard for integrity and release signing because it resists collision attacks that break MD5 and SHA-1.
Yes. FolderManifest hashes every file in a folder tree and writes the results to a manifest you can re-verify later. That makes it suitable for release artifacts, evidence packages, and migration bundles where you need to prove thousands of files in one pass.
Yes. FolderManifest runs locally on your Windows or Linux machine, so private, client-owned, or regulated files never leave your computer. The desktop app and the CLI both work without an internet connection after install.
Download FolderManifest and turn your next file or folder check into evidence you can share.
