I mentioned that the scene would be empty. You would rebuild the scene by dragging items from the Components panel.
The new file is less successful, and the recovered parts are less than half the size of the original file. It also has an empty scene, and you would rebuild it from the Components panel:
@daveR thnx, i understand this, but there were no parts for the loss of which i am so worried))
What do you mean by no parts? The In Model Components shows a lot of components. Groups and loose geometry aren’t recovered.
Exactly, i mean what in recovered model i don’t have object which i want to repair, next time i will use for all important geometry components not group.
So you don’t want any of the components that are in your model? That means there is over 47 Mb of unneeded stuff. Your corrupted file wasn’t much larger than the recovered one. That would make me think that there wasn’t much to your model. You should make sure you purge unused stuff from your models periodically. That could help to avoid corrupted files. Also make sure you are saving the file to an internal drive and not to the cloud.
Thank you for helping me so quickly with this 
Hi, I need help. Same problem. File wont open “unexpected file”.
I’m using SketchUp 2015. And I saved my file using 2015 as well.
Pls help me! Thank you!
Can you put the file online somewhere that I can download it? Also, look in the same folder as the SKP file, and see if there is an SKB file. You could rename that to end with .skp instead of .skb, and that file may open.
Oh god, I think my file has corrupted, too. I thought they were backed-up online. Is there any chance you can rescue anything from the file? It won’t open at all for me. Thank you.
You’re using the free web version of SketchUp as indicated in your profile?
Yes, that’s right.
It opens fine for me.
Is this your backyard? I like the toy Airstream trailer.
I expect all those plants are overloading the web version.
Great 
But when I try to open it in Sketch-up Online it says this ‘This does not appear to be a SketchUp model!’
Try this one.

Nice hobby project, by the way. I wish palm trees would grow in my backyard.
Thank you so much. I’ve been able to open your file online. So I should be saving back-ups offline, which option from the menu should I use to do that Export or Download, and which file format should I save in? I don’t want another scare like, I was about to cry all evening!
You can download the .skp file to save it as a backup.
Don’t let this play time get you down.
It’s not my garden unfortunately - it’s a design for a friend’s garden. They are planing to get the airstream, too.
There are a range of hardy palms that you can grow in cooler climates, by the way, if you really want some palms in your garden
Are they getting a minature Airstream? The one you show in your model wouldn’t be large enough to stand up in. It’s less than 1 meter tall.
I will back-up religiously from now on 
None of it has been drawn with accurate measurements. The design is just to show the style that I think they want. Lots more work to do on it yet. But I will be making it bigger. I had just imported the airstream when it crashed - maybe that’s why it crashed…
