The .tcr filename extension is a compressed text file format for eBooks and text associated with eBook reader software developed by Psion, a London based techonology company. The format has its beginnings in the early 90's and was designed for use on the PDAs released by the company, particularly the Series 3 handheld PDA. Though the format is proprietary and was intended for exclusive use on Psion devices, today, a few eBook reader applications can open files encoded in this format. As PDAs eventually lost there popularity, the format was discontinued when Psion eventually pulled out of the PDA market.
The .fb2 filename extension refers to the open XML based eBook format known as FictionBook. The file format was developed by Dmitry Gribov with an initial release in 2004, quickly gaining popularity in Russia. The format is open which in this context means it has no compatibility with digital rights management technologies. The structure of the format splits the contents of the data into three sections; title information, XML document information, and finally information about the paper edition which is optional.

The TCR format boasted of better compression of files saved in this format in comparison to its closest rival at the time, PalmDoc. The format is an adaptation of the ZVR text file viewer format developed for Psion, but incorporates the compression algorithms used in the TCReader program which was faster than that used on the ZVR format. The company claimed a 50% on average saving in memory storage after compression to TCR.
Being extended from the XML format, the FictionBook file format describes the structure of the documents content, supporting metadata such as author, title, as well as special tags for quotations and epigraphs. Unicode is the supported character set used with the format. To display supported raster images, the images are first converted to a base 64 stream and contained within a binary tag. Plain text data typically loads first, being located at the top of the file with images allowed to load later in sequence.
