If the data is extremely valuable (business-critical), hire a digital forensics firm. They can attempt recovery legally without exposing you to malware.
This method utilizes a pre-compiled list of words (a dictionary file).
ElcomSoft offers a fully functional trial of ARCHPR that can recover short passwords (up to 4 characters for some formats). For longer passwords, consider purchasing a license. The cost is far lower than the damage from malware. advanced archive password recovery serial key 454 full hot
Specific to weak encryption implementations (like ZipCrypto), this attack requires the user to possess at least one unencrypted file that is also contained within the encrypted archive. The software compares the known plaintext against the ciphertext to deduce the encryption keys.

The official ElcomSoft trial can recover short passwords (up to 4 characters for some formats) and show you the methodology. That might be enough if your password was simple. This method utilizes a pre-compiled list of words
The efficacy of password recovery software is heavily dependent on the specific encryption algorithm used by the archive format.
Modern recovery tools leverage Graphics Processing Units (GPUs) rather than Central Processing Units (CPUs). GPUs are designed for parallel processing, allowing them to handle thousands of threads simultaneously.
