A. The new method of packaging files is to store them in a CAB file, what is a non-proprietary format based on Lempel-Ziv compression. Both DriveSpace and DoubleSpace also used Lempel Ziv based compression algorithms.

A common way of extracting files is to use a tool such as WinZIP which supports extraction of CAB files but new to the Windows NT Resource Kit is Extract.exe (as of supplement 4) which can also extract files from a CAB file.
