Checksum Calculator5.0f

Checksum Calculator is a feather-light and portable application you can use to calculate the CRC32 checksums of multiple files at the same time, which is useful for validating file integrity. It has advanced options for experienced users.

Process multiple files in bulk

Its interface is outdated but fairly intuitive to use, especially if you've worked with hash tools. One or more files can be added to the task list with the help of the classical file browser.It's also possible to indicate directories with numerous files to add at once, include or exclude subfolders, as well as to exclude directories or files by extension.

Save and compare results, configure settings

Calculation tasks don't take long, depending on the amount of files. Meanwhile, results can be saved to file, copied to the Clipboard, sa well as compared with other saved files. Profiles with the current settings can be saved and later reused.Moreover, you can ask the tool to ignore new files in the checksum comparison results, autosave file lists, as well as to calculate CRC16, full-byte addition hashes, or 4-digit EPROM byte addition hashes instead of CRC32. It's also capable of generating CRC16 and CRC32 signatures compatible with PKZIP and MAME. Command lines are supported.

Portability benefits

Since there's no setup pack involved, the downloaded files can be copied to a custom location on the disk or to a removable storage unit, in order to run Checksum Calculator on any machine with as little effort as possible. It doesn't alter your system registry configuration or create files on the HDD without notifying you.

Evaluation and conclusion

If it comes across a file it cannot open during a bulk operation, it stops the entire task instead of skipping to the next file. We've also encountered some compatibility issues with newer Windows editions. Too bad that Checksum Calculator hasn't been updated for a long time.
