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 12 adds new features for JPEG compression, the ability to ZIP files directly from a digital camera, an enhanced thumbnail view, a built-in image viewer, support for the LZMA compression method, customizable password policies, more encyption options, and other new features.
