The Ultimate ZIP Cracker is a speedy password recovery software that can retrieve lost passwords for various file types. It can recover passwords for MS-Word and MS-Excel documents, as well as ZIP, RAR, and ARJ archives.

To streamline the recovery process, the Ultimate ZIP Cracker offers several search methods. The Password Wizard provides easy step-by-step password recovery, while the Brute Force Attack method tests all possible passwords. Smart Search tests all "pronounceable" passwords, and Dictionary Search can use either the built-in or an external dictionary. An additional feature, Date Search, applies more than 5,000 date formats to a given date range, and Customized Search will use your own search templates.
The Guaranteed Decryption method is capable of decrypting .DOC or .XLS files regardless of the password used, and it operates at an impressive speed on Pentium 4 systems. Plaintext Attack is a unique feature that decrypts the entirety of an encrypted .ZIP file, provided the user provides another unencrypted ZIP file (termed plaintext file) containing at least one file from the encrypted archive.
The Ultimate ZIP Cracker offers a free trial version, which can reveal passwords of up to 5 characters in length. For passwords exceeding 5 characters, users must purchase the full version.
