If you work with a large number of compressed archives (.zip .arj .rar) and are concerned with the integrity of those files, then CRCheck32 will make your life easier. CRCheck32 automates the process of finding and testing archives which may be spread over multiple directories. This version has been completely rewritten in Delphi 5.0 and has everything the original CRChecker had plus more. Some of the features include:

• Automated testing of an unlimited number of archives.
• Support for .zip, .arj, and .rar's
• Ability to CRC check entire directories or individual files.
• Recursively search drives and directories for archives to check.
• Error Log reports all files with errors.
• Auto rename or delete of bad archives.
• Supports the testing of password protected archives.
• Command line support.
