7-Zip is a free and open source file compression app that you can use to achieve very high compression rates with virtually any type of file. Unlike other similar programs, you don't need to register or purchase 7-Zip in order to use it. Once you install it on your computer, you can use it personally and professionally without restrictions of any kind. Once you've installed 7-Zip, you can use it directly from the context menu by right-clicking on any file, whether it's compressed or not. If you right-click on a compressed file in a supported format (7z, ZIP, CAB, RAR, ARJ, GZIP, BZIP2, TAR, CPIO, RPM, or DEB), you'll see a series of options, such as decompressing directly in the file's directory or decompressing in a separate folder. If you right-click on an uncompressed file, you can easily add it to a compressed file. There are tons of options for adding documents to a compressed file. Of course, the first thing you have to do is choose a name for the compressed file you want to create; after that, you can choose the desired output format, the compression level, the compression type, and more. You can also encrypt the file using a password, or you can split it into fragments of different sizes. One of the most interesting aspects of 7-Zip is the degree of compression it can achieve with certain formats, which far exceeds that of other similar tools. It's important to keep in mind that this is usually a double-edged sword, because, generally speaking, the more a file is compressed, the longer it takes to decompress. The difference, in any case, is minimal, especially if you take into account the amount of disk space you can save. 7-Zip is one of the best compressors out there. This program is completely free, offers a large number of features, and takes up very little space on your hard drive. For all these reasons, it's one of the best file compression tools you can find.
