Duplicate File Detective provides a simple File Hash Calculator that you can use to compute the checksum of one or more files.
Using the File Hash Calculator is a good way to get familiar with file checksum concepts, and can also provide you with a rough sense of the time differences required to perform each type of hashing computation. This information can help you make better decisions on what types of file matching options to use in your projects.
To use the File Hash Calculator, select the hash types you wish to have produced, enter one or more file paths, and click the Compute File Hashes button. The file hash results area will show the requested hash type for each file.
