Archive

An Achive is essentially group of files, bundled together as one, in some format. Once all the files are together, you can encrypt or compress all of them at once, as encrypting or compressing can only be done on a file-by-file basis and you almost always get better compression on the archive than you would by compressing each one then archiving the results, this is one reason why archives are so common, in one shape or another.
