What is a CMR file?

CMR files mostly belong to Crayon Physics Deluxe. CMR files are container files that store data for application-specific uses.
Depending on the software, these files may hold game data, measurement information, cutting optimization layouts, performance results, or screen recordings.
For example, game data files from Crayon Physics Deluxe use zlib compression to pack game content. Similarly, Clickteam Fusion uses a similar approach for game level data.

Game Data: Used to store assets and levels in games (e.g., Crayon Physics Deluxe available at Crayon Physics Deluxe).
Measurement Data: Holds measurement results such as Calipri data or train reports, often using ZIP compression.
Cutting Files: Contains layouts and optimization details from tools like CutMaster2D (employing XML; more at CutMaster 2D).
Result Files: Stores output from performance measurements (e.g., Coach 6 results with details at CMA Coach Measurement Results).
Recording Files: Holds screen recordings from Camtasia Studio, linked to configuration backups (TechSmith).

FilExt.com tips: These files do not follow a single standard. The internal format (zlib, ZIP, XML, or none) depends on the application that created them. To view a CMR file correctly, use the appropriate tool or software that matches the file's origin.

How to open a CMR file

You need a suitable software like Crayon Physics Deluxe to open a CMR file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your CMR file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CMR file directly in the browser:. Just drag the file onto this browser window and drop it.

CMR file format details:

A file format defines how the data in the file is structured. The file format can be determined based on the file extension and the signature (the first few characters of a file). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. If there are problems opening a file, you must first determine the file format used. Our examination of the CMR files comes to the following conclusion:

CMR is not a commonly used file extension and covers different formats for different programs. However, the following two file formats are common:

35% of all CMR files store the data in the zlib file format. Zlib is a compressed archive file format that supports several different data compression algorithms. zlib is also a crucial component of many software platforms, including Linux, macOS, and iOS. These files are binary files, so they do not contain text, but only cryptic characters. The files are often between 35 KB and 190 KB in size. The file type was developed only in the last few years. An example of a file name is Background1.cmr or Enemy1.cmr. These files are often associated with world.
15% of all CMR files are based on the zip format, so several files are compressed and saved in one CMR file. 4 to 29 compressed files are common. File names inside are history.html, plan.md5 and plan.xml. You can see the included files and images by renaming the file extension to .zip and then double-clicking it. The file size is in the range of 410 KB to 2 MB. The keywords tmpUT are typical for these files. Files like these are sometimes connected to wheel, and often consist of personal data.

All the rest of the CMR files (50%) have different formats, the following 5 formats can be found: SeeYou Raster Map, XML and CMA. If you want to find out which format your CMR file belongs to, just click on the button "Choose your .cmr file to view".

How to solve problems with CMR files

Associate the CMR file extension with the correct application.
Update your software that should actually open multi-purpose container files. Because only the current version supports the latest CMR file format. Search, therefore, e.g. on the manufacturer website after an available Crayon Physics Deluxe update.
To make sure that your CMR file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
