Windows GUI utility to hash files and folders, write sidecar hash files, and export results to CSV.
FileHasher computes cryptographic hashes for individual files or whole folder trees, writes .sha256-style sidecar files, verifies existing sidecars, and exports results to CSV. It can optionally open .msi installer packages read-only and hash the files contained inside them individually. Ships as a signed, self-contained single executable; no .NET runtime install is required.
Adds a Subfolders control so folder scans can cover everything, the chosen folder alone, or a set number of levels, and remembers your algorithm and metadata choices between runs. The Browse dialogs now open at the path already in the box, and the window no longer opens taller than the screen at high display scaling.

Fixes the window layout at display scaling above 100%, where buttons and labels could previously be clipped or overlap.
Adds an in-app help window (F1), a Verify Sidecars mode that re-checks files against their existing sidecar hash files, a results context menu (open Explorer/PowerShell/cmd at a file, copy hash or path), an extended sidecar format carrying modified date and size, and sidecar suggestions that follow the selected hash algorithm.
First release distributed via winget. Adds a signed MSI installer with Start Menu integration and clean upgrades between versions; hashing features unchanged from 0.2.x.

The download button links to the official installer published on github.com, the same file Windows Package Manager installs. You can verify the downloaded file by comparing its SHA-256 checksum with 4c51cb3fbae28000230fc9b6db98433eac69f3302b21000c500a9d7974bb8406.
FileHasher requires Windows 10 version 1809 or later and is available for 64-bit (x64) systems.
Run the offline installer with msiexec /i "FileHasher-0.5.0.msi" /quiet /norestart, or install it with Windows Package Manager: winget install --id=FSPProductions.FileHasher -e --silent.
Open Settings › Apps › Installed apps, find FileHasher and select Uninstall. From the command line, run winget uninstall --id=FSPProductions.FileHasher -e.
