What is Whirlpool File Checker?
This file integrity checker uses Alternate Data Streams to store the hashes of your files. So, it only works on NTFS volumes. With that, you can rename, copy or move your files (to another NTFS volume) without losing the hashes, and without needing to do anything else.
Each folder is recursively processed. You can use drag-and-drop, mix files and folders, pause and resume.
The project seems to be no longer updated. Last version, 0.3.1, released in May 2014, can be still downloaded from SourceForge
