Checksum Calculator

Checksum Calculator is a super lightweight and portable tool that helps you calculate CRC32 checksums for several files all at once. This is really handy when you want to check if your files are intact and haven’t been messed with. Plus, if you're an experienced user, it has some advanced options that might be right up your alley!

Simple Interface

The interface might look a bit dated, but don’t let that fool you! It's pretty easy to use, especially if you've played around with hash tools before. You can add one or more files to the task list using a classic file browser, which makes it straightforward.

Add Files Easily

You can also point to folders filled with lots of files and add them all at once! Want to include or exclude subfolders? No problem! You can even filter out certain directories or file types by their extensions. This makes organizing your checksum tasks a breeze.

Quick Calculations

Calculating checksums doesn't take long at all—it really depends on how many files you're working with. Once the calculations are done, you can save the results to a file, copy them straight to your clipboard, or even compare them with other saved results. If you like keeping things tidy, you can save profiles of your current settings and reuse them later!

Extra Features

You can tell Checksum Calculator to ignore any new files when comparing checksums. It also has an autosave feature for file lists and can calculate CRC16 and other types of hashes instead of just CRC32. If you're into more technical stuff, it supports command lines too!

No Installation Needed

No need for a setup pack! You can just download it and place the files wherever you want on your disk or even on a USB stick. This means you can run Checksum Calculator on any computer without hassle—no changes made to your system registry either!

A Few Drawbacks

If the program runs into a file it can't open during its bulk operations, it'll stop everything instead of just skipping over that one file. And we did notice some compatibility issues with newer Windows versions. It’s too bad this tool hasn’t seen an update in quite some time.
