Description
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.
A KEPUB file is an EPUB ebook with extra Kobo markup (koboSpan elements and a kobo.js script) that Kobo e-readers use for their faster renderer, page statistics and highlighting. It is usually saved as .kepub.epub; any EPUB reader can open it.
