Description of Directory Catalog program from Softdepia.com:
Directory Catalog is a powerful utility for system administrators and other advanced users wanting to keep track of, and analyze, file and system changes. These changes can occur for a variety of reasons including normal software use and upgrades, or more menacing realities of modern computing like virus' and Trojan horses. Directory Catalog keeps a "snapshot" database, or Catalog, of all files in a directory, or multiple directories. Within each database, information is contained for each file that existed at the time the database was generated. This information includes standard file date, time, and size data, but much more importantly it can contain a "Digital Signature" of the file and, for binary files, Version Information encoded by the vendor. Any change to any aspect of a file will be detected by Directory Catalog and displayed for your analysis. It simply is not possible for something to change and not be detected. Of course, Directory Catalog also picks up on missing and new files, in addition to changes. Digital Signatures are generated using the RSA Data Security, Inc. MD5 Message-Digest Algorithm code developed by RSA Data Security, Inc. MD5, or Message Digest 5, is a powerful, fast, and extremely hard to crack code base for generating digital signatures for files, or any arbitrary length of data. This code is used in Directory Catalog, but it copyright and owned by RSA Data Security, Inc. MD5 is discussed in detail in Internet Request For Comments (RFC) 1321 available at http://www.internic.net/.
Directory Catalog is a "Free to try" program. You can download and try it for an evaluation period.
