The program is also built into Windows. You can create an archive of files and folders with a couple of mouse clicks.
There is a viewing area at the bottom of the program window. You can select the files to be archived or extracted right there. It is convenient to use the drag and drop feature.
The archiver supports many formats. Among them are 7z, RAR, ZIP, ISO, CAB, MBR, etc. It is possible to create SFX and multi-volume archives. The program automatically measures the performance of your computer while the files are being packed. The user can change the number of threads for 7z work independently.
