How to use Parallel Extraction

Usually when an archiving program decompresses an archive, as shown below, the program extracts the first file in the archive and then other files one by one in sequence.

The feature "parallel extraction" of Bandizip, however, allows the program to make full use of a multi-core CPU and extract several files simultaneously; the processing speed of the parallel extraction is 2 to 6 times faster than that of usual extraction.
