A JDR file contains video recorded by an IROAD dash camera. It is saved in the proprietary JDR format and can only be played by PC viewer, which is included with the purchase of IROAD dash cameras, and the IROAD mobile app for Android and iOS. JDR files were introduced with the release of IROAD V9 cameras.
JDR file open in IROAD WiFi PC Viewer 3.7
JDR files are automatically created by IROAD dash cameras when beginning a recording and then saved to the camera's SD card. You can insert the SD card into a computer and transfer the files to your computer. The files can be played using the PC Viewer or the IROAD mobile app.
Since JDR files are not supported by other players, you can also convert JDR files to the more widely supported .AVI format using PC Viewer or the IROAD mobile app.
