Create Archive

Use the command “a” to add files to archive. If archive if file name given does not exist new archive will be created otherwise files will be added to existing archive

$ 7z  a  archive.7z file_to_compress

$ 7z a -pPASSWD archive.7z folder

Create archive with sub directories

$ 7z a -r archive.7z.  folder
