Can't find .skb file

I’ve updated to Windows 11 after my ssd failed totally.
I can no longer find my .skb file. In Preferences I have Create Backup set to every five minutes.
.skb files from previous projects are visible.

Is there a reason you are looking for the backup file? You shouldn’t need it unless SketchUp or your computer crashes.

Create BackUp only means it will start saving the prior version of your model when you manually save (Ctrl + S or via the file menu)
There is only one backup file per model, located in the same folder.
Autosaves are temporary files used in case of a poweroutage or crash that will update every interval (standard 5 min after the last edit)
They get lost if the model is saved successfully.


OK, got it. Thanks
