FCPro

FCPro is a command-line binary file compare 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. It can prompt to confirm each error and provide detailed relevant information, select files by wildcards, attributes, range in size or date and time, or whether they have been compared before, and provide information in a simple and smart way, so you can understand the results at a glance.
