BlakHole

BlakHole is a fairly obscure archiving format supported by a handful of multi-format archiving programs. Similar to some other formats such as ZIP and ARJ, BlakHole puts multiple files together in one compressed file. It's a proprietary format from the ZipTV Compression Components - a library for Delphi.
