WinZip is the original and most popular of all Windows ZIP file utilities. Wizard/Classic interfaces accommodate both first-time and experienced users. With WinZip you can quickly and easily compress and decompress files, folders, and entire folder trees to save storage
space and reduce e-mail-transmission time, as well as encrypt and decrypt your sensitive documents. Features include tight integration with Windows Explorer, support for most Internet file formats, and one-click zipping and e-mail. WinZip 11.1 offers a thumbnail image view and automatic compression selection, plus improved compression for audio files (.WAV), the ability to open .BZ2 and .RAR files, and the option to try WinZip E-Mail Companion.
