What is 7-Zip

An open-source, free to download, file-archiving utility designed for compressing digital data, reducing files to a more manageable size.

7-Zip supports all of the popular file compression formats, including ZIP, but also promotes its own high-compression format for archiving individual or groups of files. The utility features a small installation package that belies a surprising number of features and functions. In short, 7-Zip is a free archiving option that rivals its better known, often costly, contemporaries.

The interface of the program places commonly used tasks on a control panel that runs from left to right across the top of the file browser window. From here, a user can archive, extract, test, move, copy, and delete data. Furthermore, it allows the user to manipulate files in order to create compressed archives for easy storage or migration to another computer. The layout of the interface may be sparse, but it uses a familiar file explorer configuration that any computer user can quickly get to grips with. Simply manage files and archives within nested folders and directories, intuitively locating a document or an image on the Desktop, or navigate to any chosen folder and data with a few clicks of the mouse. Those more comfortable with a command line environment can bypass the mouse and directly enter command inputs that result in the same level of functionality.

While there are many examples of file archivers available, each with a reputation for high-performance and a long list of features, 7-Zip finds its place in this competitive market with a well-earned reputation for versatility. One leading file archiver may support the RAR format, with another managing the ZIP format, but 7-Zip can manage and manipulate both of these formats, adding TAR and ISO to an impressive number of supported archive formats. On top of this essential capability for coping with different archive types, 7-Zip uses its own 7z format, an archiving standard that features high-compression ratios and AES 256-bit encryption. Other noteworthy features include compatibility with Windows and Linux and a low processor overhead that allows the utility to show off speedy performance.

Market dominance may favor several other alternatives, but none have the simplicity of operation and the versatility that 7-zip has. Additionally, there are two versions of the software. That is, one offers 32-bit compatibility, while the other is a 64 bit variant. For those that view the simple user interface as a disadvantage, tap the F9 key and the computer screen is transformed into a more advanced dual-panel layout.
