7 Best Free Open Source File Integrity Monitoring Software For Windows

Here is a list of best free open source file integrity monitoring software for Windows. File Integrity Monitoring is an important process through which users can find out whether a file is modified or not. This process helps IT professionals to check if a file is corrupted or modified due to viruses or malicious programs. Sometimes, the changes on files occur on bit-level which is almost impossible to detect manually by users. To detect even minute changes in files, you can use file integrity monitoring software. This list contains specifically open source file integrity monitoring software, which means you can access and edit their source code without any restriction.

In some software, you get a direct file integrity monitoring feature that compares files and shows the final result. In other software, you need to first generate a hash code of files using a common hash algorithm. After that, you need to manually compare their hashcodes to detect any changes between the two files. The process to monitor file integrity is quite simple in all these software. Still, to help novice users, I have included the necessary steps in the description of each software.

Apart from checking the file integrity, you can also use these software to generate hash code of files using various algorithms like MD5, SHA1, SHA256, SHA512, etc. A few software also lets you generate hash codes of plain text. Go through the list to know more about these open source file integrity checker software.
