The .mobi filename extension is an eBook file format developed by French company MobiPocket for their ebook readers for mobile phones and PDAs. The company was later acquired by book reseller and online store company Amazon in 2005, a deal which included the mobi format asset. The mobi file format is mostly associated with the mobipocket software package as well as early versions of Amazon's kindle ebook reader device. The format is considered cross platform given its compatibility with several devices including most smartphones that have compatible readers installed. But although mobi files still exist in circulation, the format was superseded by Amazon's AZW format when support and further development of mobi ceased in 2011.
The .ZIP file extension format is a file archive and data compression format originally developed and released in 1989 by Phil Katz. With compatible zip format software, a file or a group of files can be packed (compressed) into a single .zip archive which can later be unpacked (decompressed). The zip file archive format facilitates the distribution of multiple files as single archives particularly over the internet and networked systems. Many operating systems have native support for the file format and can usually open zip archives without the need for third party software. Microsoft windows for instance has had native support for the ZIP format since Microsoft Windows 98, similarly Apple's Mac OS includes ZIP support through its default archive file handle Archive Utility.

The mobi file format extends the popular HTML specification adding DRM protection support. It includes advanced file navigation support such as indexing, book marks, notes, and annotations. The format is adapted to reflowing content layout to optimally use the screen size of its device, but it has a hard limitation of 64 kilobytes for images which may cause image files to incorrectly display on larger displays such as tablets and pc monitors.
Many other common filename extensions use the ZIP format in one aspect or another, for example JAR, .WAR, .DOCX, .XLXS, .PPTX, .ODT, .ODS, .ODP all utilize the ZIP format. The ZIP format provides for data integrity through the CRC32 specification with support for digital signatures. It also supports multiple compression algorithms but commonly utilizes the DEFLATE algorithm.
