Extracts files from an archive with their full paths in the current directory, or in an output directory if specified.
See the e (Extract) command description for more details.
7z x archive.zip
extracts all files from the archive archive.zip to the current directory.
7z x archive.zip -oc:\soft *.cpp -r
extracts all *.cpp files from the archive archive.zip to c:\soft folder.
7-Zip doesn't use the system wildcard parser. 7-Zip doesn't follow the archaic rule by which *.* means any file. 7-Zip treats *.* as matching the name of any file that has an extension. To process all files, you must use a * wildcard.
