Specially created for developing textbooks known as "Print Replicas" on the Kindle eReaders and desktop application with DRM protection. AZW4 used both PDF and MOBI technologies.
The TCR file format is associated with eBook files specifically used by Psion Series 3 devices. Psion Series 3, a range of personal digital assistants (PDAs) developed in the early 1990s, utilized these files to store and display electronic books (eBooks). TCR files are designed to be compact to suit the limited storage capacities of early PDAs. They contain the text of the eBook, and possibly basic formatting, optimized for the low-resolution screens of the Psion device.
