Compress and decompress
7-Zip is like WinRAR or WinZip, but totally free. In addition, it supports more formats . You can compress files and folders in 7Z, ZIP, BZIP, GZIP, TAR, WIM, XZ and ZIP format. As for unzipping, the list includes all of the above and adds RAR, DMG, CAB, ARJ, ISO and other lesser-known formats.
Compressing files you can choose from several levels of compression, which included the Ultra mode . This takes longer to compress and decompress, but in return gets the best compression.
7-Zip allows you to configure in detail how you want to compress your files. In addition to choosing the format and level of compression, you can also adjust other more advanced options such as the size of the dictionary, the size of the parts (if you want to compress it in several blocks) and the password.
You can also create self – extracting EXE files , very useful if you want to share your files with other people and you’re not sure if they have 7-Zip installed.
From the window or from the browser
7-Zip works much like WinRAR and WinZip. You can use it either from the main program window, the Start Menu, or from the file explorer itself.
The easiest and fastest way to use 7-Zip is through the contextual menu of the browser. First you select the files you want to compress, and then compress them with 7-Zip from the context menu. Decompression is even easier, when the program has been associated with the supported formats.
