Batch Checksum Tool
Batch Checksum Tool: SHA-256 for Hundreds of Files at Once
FolderManifest is a batch checksum tool that generates SHA-256 and MD5 hashes for hundreds of files in one pass, exports a manifest you can verify in CI/CD, and runs from both a GUI and the command line on Windows and Linux.

SHA-256 and MD5 for every file
Pick the algorithm and hash hundreds of files in one batch. No looping scripts, no manual Get-FileHash per file.
Manifest export for CI/CD
Write a manifest once, then diff it in CI to catch any file that changed between builds. Verification becomes a one-liner.
Command-line and GUI
Point and click for a one-off scan, or script the CLI for repeatable checks across releases, migrations, and audits.
Frequently Asked Questions
What is a batch checksum tool?
A batch checksum tool generates hashes for many files at once instead of one at a time. You point it at a folder, pick an algorithm such as SHA-256 or MD5, and it hashes every file and writes the results to a manifest. FolderManifest does this for hundreds of files in a single pass on Windows and Linux.
How do I checksum multiple files at once?
Open FolderManifest, select a folder, choose SHA-256 (or MD5, SHA-1, CRC32), and run. Every file is hashed in one batch and the results export to a manifest you can diff later. The same job runs from the GUI or the command line, so you can script it for repeat checks.
Can I export a checksum manifest for CI/CD?
Yes. FolderManifest writes a manifest listing every file and its hash. Check the manifest into your repo or publish it as a build artifact, then verify it in CI with a one-line diff. If any file changed between builds, the manifest tells you exactly which one.
Does the batch checksum tool work from the command line?
Yes. FolderManifest ships a CLI alongside the GUI, so you can hash a folder and write a manifest from PowerShell, CMD, or any CI runner on Windows, and from bash on Linux. The same command produces the same manifest every time, which makes repeatable verification straightforward.
Which checksum algorithms are supported?
FolderManifest supports SHA-256, SHA-1, MD5, and CRC32. SHA-256 is the default for integrity and release verification because it has no known collisions. MD5 and CRC32 are kept for legacy compatibility with older manifests and tooling.
