| Description | Psion developed the .tcr file for use with their Series palmtop devices, which were created in the 1990s. The main purpose of creating this format was for device use, but some eBook readers can still display .tcr files. However, the file format became outdated after production of the palmtop devices ceased. |
| Technical details | The ZVR format served as the foundation for the development of TCR. TCR allows for compression ratios of approximately fifty percent, which is relatively better than PalmDOC. TCR faced significant competition from other formats when it was first introduced. To open a TCR file, one must use appropriate software, or else a notification will be displayed. To correctly open a TCR file, simply right-click or long-press the file and select the desired application. |
