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 .rb extension is used for many formats which include definition files based on the Fuzzy rule, eBook files of the Rocket Edition, class files of Ruby on Rails, project files of REALbasic and the profile configuration files of Rosebud. Other versions of Ruby which are also called gems include Mongrel, Capistrano and Ruby on Rails.

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.
