Name: CorelDRAW templates files (7-X3,X4 versions); Psion Series 3 eBook File

Description: This is a vector imaging format used in the CorelDRAW editor. It has a template that can be applied for other designs, including styles, grid parameters, page layout and other parameters. The CDT template allows for the creation of several images in one style without changing the settings in manual mode.; 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.
