Self-extracting archives
(in addition, some of the other archivers are able to produce executable files for some platform which include the archived data and a program to extract them, and generally have the file extension normal for executables, such as .exe for DOS/Windows. In many cases, if you rename the extension to the appropriate one for the archive type involved, e.g., .zip, the file will open in the appropriate archiver, which is handy for extracting them on systems not compatible with the original executable.)

Transfer encodings
(convert binaries to printable ASCII for download; encode resource forks or metadata together with file, etc.)
