The advantage of the free and open-source 7-Zip compression program is that it has a very wide range of features. It not only lets you compress files, but also encrypts them. Furthermore, it is compatible with many formats such as ZIP, TAR, WIM, XZ, GZ, BZ2, APK, DOCX, JAR, RPM, ISO, DMG, FLV, SWF and DEB for compression and decompression, as well as RAR, ARJ, CPIO, LZH, LHA, MSI CAB and EXE for decompression only. If you want to use this program, you have the choice between a version with installation and a portable version from 7-Zip.
Two major advantages of 7-Zip: you have the possibility of creating unmounted and self-extracting archivesas well as encrypted archives. The ability to split a 7z file into multiple sub-archives ensures even faster transfers. The self-extracting feature can be used by saving the files as EXE files. You can access the data contained in the file with a simple double-click. Then, AES encryption with a 256-bit encryption key including password protection guarantees a high level of security. This method is made particularly intuitive and clear by the file manager and its graphical interface.
