checksum was given nothing to do!

By default, you get to this page when you launch checksum with nothing to do - no explorer context menu, no drag-and-drop, no command-line, nothing!

For full details about how to use checksum, see here. It is simple.

If you are not using the explorer context menu actions (or drag-and-drop), you need to provide command-line switches. Full details of the available command-line switches are here.

NOTE: You can customize what checksum does when launched with nothing to do, so instead of this page, you could have it perform some other task. All the details are inside you checksum.ini (preferences file).

More details about checksum.ini can be found here and here.

Have fun with checksum!

Welcome to!

Since switching hosts (I hope you are alright, Ed! Wherever you are …) quite a few things seems to be wonky.

Juggling two energetic boys (of very different ages) on Coronavirus lockdown, I'm unlikely to have them all fixed any time soon. Mail me! to prioritise!
