finding a link or material pointing to a missing file or path In packing a blend file I get a report of 3 missing files (actually, only paths) from an FBX imported from a 3dsMax export:
Error: Unable to pack file, source path 'C:\Users\James\Documents\3dsMax\projects\architecture\scenes' not found

(aside: this path actually exists)
I am not getting any console output in 2.90 for &quot;List Missing Files&quot;.   Is there some way I can discover what material or other file pointer are causing these errors so that I can correct them?
In the outliner choose the Orphan Data display mode

To fix the path for broken links or missing items use the Data Api mode

Data API
Lists every data-block along with any properties that they might have.
Orphan Data
Lists data-blocks which are unused and/or will be lost when the file is reloaded. It includes data-blocks which have only a fake user. You can add/remove Fake User by clicking on cross/tick icon in the right side of the Outliner editor.
