FCPro 1.2 was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this software available. The software lies within System Utilities, more precisely File Managers. We recommend checking the downloaded files with any free antivirus. The actual developer of the software is Coleap.
From the developer:
FCPro is a command-line binary file comparison tool. With improved file access methods, it is very fast. It does not use the file system cache, instead it reads directly from disk media, so you can identify corrupted files caused by defective disk media.
You may want to check out more software, such as Quifilt, which might be similar to FCPro.
