PKZIP is an application which enables you to compress files and extract content from archives.

The user interface of the program is clean and intuitive. You can compress files and emails by using the file browser.

So, you can select the compression filter between "no filter", "standard" and "advanced".

Furthermore, you can load a list of files to compress from a text document (with the possibility of creating an inclusion or exclusion list).

In the "Options" menu, you specify the compression level ("normal", "speed", "fast", "maximum", "custom") and set the add mode when selecting files (e.g. freshen existing files only, update existing files and add new ones, include subfolders, clear the archive attribute).

In addition, you can set the archive date (e.g. newest file date), split size, diskette format, end of line, file name conversion, file attributes preservation (e.g. archive, hidden, read-only) and other options (e.g. enable auto save and to store file times).

Plus, you can encrypt files and select the encryption algorithm. Settings can be restored to default at any time.

Moreover, you can extract files from an archive, test them for integrity or install them. PKZIP also lets you organize archives (copy, move, delete, view properties), change the viewing mode (Explorer or classic view, thumbnails, large icons), create and manage favorites, and more.

The program uses a low-to-moderate amount of system CPU and memory, includes a well-drawn help file and we haven't come across any errors during our tests. We strongly recommend PKZIP to all users.
