18 Best Free File Integrity Checker Software For Windows

Here is a list of best free file integrity checker software for Windows. The integrity of a file is checked in order to confirm that no change is occurred in a file due to any reason. To check file integrity, these software compare the original hashcode of a file with the current hashcode. If even a single bit is changed in a file, its current hashcode will be different than its original hashcode.

In order to verify file integrity, these software also use different algorithms like MD5, SHA1, SHA256, SHA384, CRC32, etc. While verifying the file integrity, you need to use the same algorithm that is used to generate the original hashcode of a file.

These software can also be used as hashcode generator software as they generate hash codes of files. Some software are also capable of calculating hashcode of text data. Besides this, you can find additional features in these software like Compare Files, Password Generator, Encrypt Text, Log Generator, etc.

In general, these software are quite simple to use and you can easily use them to check file integrity. To help you out, I have mentioned the steps to check file integrity in the description of each software. Go through the list to know more about these software.
