How to Decrypt a Zip File

By Raul Avenir

Zip file is a data compression and archive format. The file size is compressed in order to save storage space and allow faster transferring across a network or over the Internet. Most Zip file compression programs also allow the files to be encrypted while the file is being compressed as an added security feature. Decrypting the Zip file is as easy as entering the correct password, but there are times when the password is forgotten. Decrypting a Zip file without a password is not easy, but can be done with the right software.
