This software is an intuitive and customizable data verification app that allows users to create and verify SHA1, BLAKE2, and MD5 checksums for files, folders, and drives with ease. It's fast, powerful, and user-friendly.

Not only is checksum lightning fast and intuitive, but it also offers complete customization options. Choose between MD5, SHA1, or BLAKE2 hashing algorithms and take advantage of true point-and-click hash creation and data verification. Plus, it features proper UNICODE file name handling and LONG PATH support, allowing you to effortlessly recurse through an entire volume.
You can even define user-defined file groups, create automatic music playlists, and integrate with Explorer context via right-click operation. And with automatic hash removal and updating, extensionless and invisible checksum file support, and intelligent log handling capabilities, using checksum couldn't be simpler.
That's not all - checksum also supports drag and drop, legacy and *nix MD5/SHA1 file handling, and CPU control. Plus, if you hold down the SHIFT key when launching checksum, you'll access its one-shot options dialog for tailoring your settings on-the-fly.
It's no wonder that some of the largest and most critical organizations on the planet trust checksum for their hashing needs. Don't wait - try it for yourself and see the difference it can make.
