Autosave to where?

I have recently installed SU 21 and upgraded to windows 10 (sadly) I have been working on a model and had a bugsplat. I had a few SU models open and I think forgot to save the main model I was working on…Bugsplat. As you can see in the image it should have been autosaving every 5 minutes. I look for my autosave and can find nothing. Am I missing something. Firstly I looked in where the file should have been if I had inadvertanly…not there. Any ideas?

I would try double checking the info under. . . >SketchUp Preferences >Files

…and I think that should bring up the option boxes for routing file location.


Just in case it’s needed Backup files have the .skb file extension. Which gets renamed to .skp as the the reactivation step.

It might also be worth it to try a Windows based Wild Card Search for… *.skb
(e.g… include the asterisk as the sole stand-in for the file name)

If you’ve saved the file at some point a backup file with the .skb extension should be created in the same directory as Jim indicates. If Sketchup crashes, a recovery file should be created in User/AppData/Local/Sketchup/SketchUp 2021/SketchUp/working/SKETCHUP/RecoveredFiles. The User/AppData directory is normally hidden on Windows but you can make it visible. If a recovery file was created, though, you should see it in the Welcome screen when you start Sketchup again. It’ll be pretty obvious.

Some extra notes to what Dave said…

The SKB doesn’t exist until the second time that you save a file. It’s a duplicate of your previous save. So for example, if you make a file at 9am, save it for the first time at 10am, then save it a second time at 11am, at that moment you now have an SKB that is a copy of the file as it was at 10am.

The recovery folder is in a hidden folder, but you can get straight there without having to change your Windows settings. Copy and paste this text into File Explorer’s path field to get there:

%LocalAppData%\SketchUp\SketchUp 2021\SketchUp\working\SKETCHUP\RecoveredFiles

That’s the manual way to get at the files. The welcome screen Dave showed is the easier way to get to those recovered files, but in the case of a new document that has never been saved, it will be named Untitled, and you may need to scroll down the recent files list to find it.

Thanks to all, with your help I now have it sorted out. I am so glad as it was such a tedious project…6 all dissimilar terrace houses and doing again from scratch would not have been a lot of fun.
