C4D file shows 'Incorrect File Structure' or 'Unknown File Format' Troubleshooting

What to do when your C4D file says “Incorrect File Structure” or “ Unknown File Format”. Sometimes files can get corrupted, this can be caused by a number of issues. Those problems might be Crashing when saving; HDD/Network failure when saving; or Plugins corrupting Save files. With iRender today, let’s find out whether there are any ways to recover some or all of the file that has become corrupted.

For Window:

  • Go to search and type CMD
  • Navigate to your Cinema 4D Program Folder (Normally program Files\Maxon Cinema 4D RXX)
  • Now, drag and drop your Cinema 4D.exe into the Terminal Window:
  • Then press space.
  • Then paste in “-loadcorruptscenes”

For MacOS:

  • Go to Search and type Terminal
  • Navigate to your Cinema 4D Application Folder (Normally Applications\Maxon Cinema 4D RXX)
  • Right-click on the Cinema 4D.app and press Show Contents
  • Navigate through Contents to MacOS
  • Drag and drop the Cinema 4D file into the Terminal Window:
  • Press Space
  • Then paste in “-loadcorruptscenes” (It should look something like the below, )

Once Cinema 4D had loaded, try to open your file, it may still say that the file is corrupt, but then it will try to load what it can. But don’t be surprised if this process may not be able to help you recover all of your files, just a part of them. 

You can take a look at this tutorial video to understand more about this process:
