Windows 7: Integrate MD5SUM To Windows Explorer Context Menu

Looking for Windows md5sum GUI version? While the Jem’s command line version of md5sum for Windows allows one to generate MD5 hash of one or more file recursively together with progress indicator, younger Windows fans might hesitate to try anything in Windows Command Prompt.

No worry, there are many MD5SUM GUI for Windows available at no license cost too, and I am going to introduce you just one of them – the HashCheck Shell Extension, natively support both 32 and 64-bit Microsoft Windows.

Indeed, I just installed it in my Windows 7 Ultimate 64-bit and like it very much.

As its name implies, HashCheck integrate file checksum verification functions to Windows Explorer shell. Having said that, one can right click the file, click Properties, and go to Checksums tab to generate and view the file checksum – not just the MD5 hash, but include also CRC-32, MD4, and SHA-1 checksum:

Similar to Jem’s md5sum for Windows, HashCheck is capable to calculate MD5 hash of one or more files as well as showing the progress indicator (so you won’t puzzle about what is going on as the checksum calculation of a big CD image file takes time to complete).

As in my test, both HashCheck and Jem’s md5sums.exe use almost same amount of time to complete checksum calculation of Windows 7 Ultimate 64-bit ISO image file (3GB), which is about 1 minute and 8 seconds on Intel E6400 Core 2 Duo with 4GB RAM running 64-bit Windows 7 Ultimate.

Besides, HashCheck allows users to optionally integrate “Create checksum file” shortcut in Windows context menu. In the Checksums tab of File Properties dialog box, click Options button:

Add create checksum file option to Windows context menu or the extended shortcut menu.

The default option is turn on “Show HashCheck in the shortcut menu” – right click the files and you will “Create checksum file…” in the context menu. As for the 2nd option (in extended shortcut menu) means that shortcut is only appearing if you press SHIFT key while right clicks the file.

The “Create checksum file…” shortcut used to generate .md5 file which contains the MD5 hash of the files. When you click on the .md5 files that associated with HashCheck during installation, the file verification will proceed automatically and then display the result in a dialog box:

The HashCheck Shell Extension is open-source software and users are allowed to customize it accordingly. Both the build version and source code of HashCheck are available from Kai Liu.
