We’ve covered tens of excellent GUI based MD5 checking utilities, however if you are a fan of command prompt, the following two portable, free, light and powerful tools come in handy, they both work on Windows 7 and Windows XP.
1, Microsoft FCIV
This lightweight file checksum integrity verifier is developed and released by Microsoft corporation, it offers the ability to compute and verify MD5 or SHA1 cryptographic checksum values of a specified file or folder/directory. It can generate MD5/SHA-1 hash values of a directory with all files and subfolders recursively.

FCIV is portable, you can copy the file fciv.exe to your system directory( for instance, “C:\Windows” ), then you can use it as a system built-in command.
You can even rename the file fciv.exe to md5sum.exe, that’s way you get a Windows clone of Linux’s MD5SUM command.
2, Fsum
This free and portable tool allows you calculate MD5 / SHA-1 / MD2 / MD4 / SHA256 / SHA384 / SHA512 / RMD / Tiger / Panama / Adler / CRC32 / Edonkey cryptographic hash value of any file or directory.
Suppose that you want to calculate the MD5 checksum value of all files in the folder “C:\Users\diggfreeware\Desktop\notepad2″, copy and paste the line below into your command prompt:
To compute the SHA-1 value of the file “D:\test\1.txt”, copy and paste the line below into your command prompt:
