7Z file is a compressed archive file format that supports several different data compression, encryption and pre-processing filters.

What is 7Z file?

7Z file is a compressed archive file format which contains one or more files, and even folders. The files and folders are bundled together as a single file for convenience in storing and downloading. With the application of different compression methods, the size of 7Z file is much smaller than the total size of the files it contains.

7Z files can be opened with 7-Zip software. The software's ability to shrink files is stunning. 7z archives are up to 40 percent smaller than their ZIP equivalents, although compression does take longer, and the highest compression settings can hog system resources. Advanced options include the ability to create solid and self-extracting archives, and to adjust the compression level and password protection. 7-Zip software also has a command line module. Though the main interface is overly simple and looks like it is designed for Windows 95, it's not hard to use and fairly self-explanatory.
