| Description | The .tcr file format was established by Psion for their Series palmtop devices, which were launched in the 1990s. This format was principally designed for utilization on these specific devices, although a certain number of eBook readers retain the ability to read .tcr files. The file format, however, fell into obsolescence when production of these palmtop devices ceased. |
| Technical details | The TCR format was engineered using the ZVR format as a blueprint. It permits compression ratios of roughly fifty percent, which denotes a more efficient compression ratio when juxtaposed with PalmDOC. At the time of its debut, TCR was confronted with considerable competition from other file formats. Opening a TCR file necessitates the use of appropriate software; otherwise, an error message will be displayed. In order to correctly open a TCR file, a right-click or a long press on the file should be performed, followed by the selection of the correct application from the ensuing options. |
