Quick Check

Your computer knows when a file finished being downloaded through different code comparisons to check integrity. These are known as checksums, used for more than just checking the status of a download session. As such, Quick Check comes as a little tool with which you can compare existing MD5 checksums to see whether or not they match.

The application completely relies on .NET Framework to function, so you need to make sure it is already on your computer before you take it for a spin. On the other hand, the application itself is portable, and you can carry it on a thumb drive to use on other computers if necessary. As such, system registry entries remain intact.

On the visual side of things, the application stores everything in a pretty compact main window, but doesn’t pose any accommodation problems whatsoever. There are two available fields, one of which is interactive so you can paste comparison code.

This means that you need some extra tools to grab the checksum, or already have it saved somewhere on your PC. Sadly, the application doesn’t really come with a generator of its own, and only compares an existing MD5 string to one for a file you load.

However, there is a workaround with which to use the application as a generator. What you need to do is simply write a random text string inside the input field, so that the browse dialog becomes available. Even though the two codes don’t match, you’re now into the possession of the MD5 checksum for the file of interest, and are able to save, or compare it later on.

In conclusion, Quick Check does indeed help you quickly check whether or not two MD5 checksums match, but it feels a little rough around the edges overall. It would have been useful to at least see a built-in calculator to avoid the unnecessary workaround.
