What is an MCR file?
The .MCR file extension represents several different file formats. Most commonly, an .MCR file is a macro script used for automation. Software like Jitbit Macro Recorder and Pulover's Macro Creator use this format to store recorded mouse movements and keyboard strokes.
Another common use is the PlayStation memory card image. The ePSXe emulator uses .MCR files to save video game progress.
Additionally, the extension is used as a Minecraft Region File by Mojang Specifications for storing game terrain, and as a macro script file by Autodesk 3ds Max.
How to open MCR files?
Because an .MCR file has multiple possible meanings, you must use the correct program to open it.
- For automation macros, use Jitbit Macro Recorder.
- For PlayStation game saves, configure ePSXe to load the memory card.
- For 3D modeling scripts, run the file inside Autodesk 3ds Max.
- For Minecraft data, use Minecraft modding tools like MCreator.
Best practices and troubleshooting
Never delete an .MCR file if you play games on an emulator, because it contains your saved game data. If your macro script fails to run, check if it was made in an older version of your automation software.
If you need to change the file into another format, we recommend file conversion to sensible target formats on convert.guru. You can convert text-based macros to .TXT files or emulator saves to .GME formats.
