  • Md5Checker

    Free Windows Website

    Md5Checker is a free, faster, lightweight and easy-to-use tool to manage, calculate and verify MD5 checksum of multiple files/folders

    Calculate and display MD5 checksum of multiple files at one time.
    Use MD5 checksum to fleetly verify whether files have been changed.
    Load, save, add, remove and update MD5 checksum conveniently.
    It is about 300 KB and does not require any installation (portable).

    What is MD5 checksum?
    MD5 checksum (MD5 hash) is a type of digests of files. It will become totally different if any modification has been made to the file, even a byte.

  • FileVerifier++

    Free Windows Website

    FileVerifier++ is a Windows application for verifying the integrity of files. FileVerifier supports various algorithms by means of dynamically loadable hash libraries. It uses the Windows API and doesn't have any dependencies other than what comes with Windows (WinFVC excluded).

    FileVerifier++ is a Windows utility for calculating hashes using a number of algorithms including CRC32, MD5, SHA-1, SHA-256/224/384/512, WHIRLPOOL, and RIPEMD-128/160/256/320. Supported hash file formats include MD5SUM .MD5, SFV, BSD CKSUM, and others.

    Current Features
    Can load and save results to and from various formats.
    Hash algorithms can be added through the DLL interface.
    Hash verification. Can load hash results and compare to what is actually on your disk.
    Color coding of validity states
    Verification considers file size, file attributes, and modification date to be significant.
    Drag and drop support.
    Recursive directory processing.
    Recursive processing using patterns.
    Calculates hashes on strings.
    Search and grep using regular expressions.
    Selective verification.
    Unicode support (recognizes Unicode file names and writes results encoded in UTF-8 (without BOM))
    Supports Windows XP Visual Styles
    Shell Integration (Shell extension).
    Can be installed using installer or without.

  • SFV Ninja

    Free Windows Website

    SFV Ninja is a SFV checksum application. It also supports MD5 and SHA-1 checksum files.


    Two verification modes. The first will verify all files in the list like any typical SFV application. The second mode will only verify any newly added files. This second mode allows you to "update" an existing SFV file without having to verify all of the files.

    Recursively scan a folder for SFV/MD5/SHA-1 files and load them all at once.

    Uses relative paths whenever possible when generating SFV/MD5/SHA-1 files.
