File extension XAR description:
The XAR file format has three main regions, The Header, The Table of Contents, and The Heap. The header is a small binary data structure that identifies the file format (file magic). The table of contents is parsed as an XML document. The heap occupies the remainder of the file. Files' data are stored in the heap.

The XAR project aims to provide an easily extensible archive format. Important design decisions include an easily extensible XML table of contents for random access to archived files, storing the toc at the beginning of the archive to allow for efficient handling of streamed archives, the ability to handle files of arbitrarily large sizes, the ability to choose independent encodings for individual files in the archive, the ability to store checksums for individual files in both compressed and uncompressed form, and the ability to query the table of content's rich meta-data.
