Error "cannot overwrite used library"

When trying to save my blend file i get this error. Can someone tell me what it means?

Im using this file for animations, but now I cant save changes to it. I use two other blender files to read the animations from this file. It was working fine until just now.

Im still unable to save changes to my animation blend file. As a temporary fix, I decided to use save_as and name the file animation2.blend

Seeing as I only need the animation Data, ill replace the old file, with a copied new one. While using the new file ill keep an eye out for changes I make so if i recreate the problem, ill have an idea of where i went wrong.

An explanation for the “Cannot overwrite used library” Error will still be much appreciated.

I think I found a solution to the problem!

At some point my animation file was linking back to itself… Though I’m not sure how I managed to do this.

To fix this problem, remove the library link of the file linking to itself. That can be done in the blender outliner.


-The blend file is linking to itself.



  • Save Attempt Fail


  • Open blender Outliner. Next to “View”-“Search”, click on the drop-box that reads “All Scenes” (by default) and change it to “Libraries”.

  • put your mouse over the path and hold Alt-key and Left Mouse Button click on it. This should allow you to edit the path.


  • Erase the path to remove the library reference.


  • You should now be able to save your file!

For some reason, my outliner was set to “Show Oops Schematic” when I opened it. This may come as a second problem to someone not familiar with blender’s outliner interface. Click “View” -> “Show Outliner” and it will show the outliner as seen in the screenshots.
