Unexpected file format and bug splat when opening skp file

I know there was a long thread about this and I read all the replies. I couldn’t find where to make a new post.

It looks like Colin has helped others recover parts of their files. Here’s what happened to me:

Was working on a file last night. Tried to open it this morning and got the unexpected file format message and even a bug splat when trying to open it. The file that comes up is completely blank, with no components or materials or anything that I can see in the drawers on the right. Am on deadline (of course). Would greatly appreciate your help if there’s anything you can do. The file has been saved to my laptop. I guess it’s also in OneDrive, but I’m always pulling up the one that’s in my Personal area.


Many thanks, Jana Sansbury here’s the file:

Do you have the backup copy of the file? It’ll have the .skb file extension.

I looked in my files and I do not for some reason

Did you look in your OneDrive folder?

Are you sure that the file is save on your local internal drive and that you aren’t just saving/working on it directly from OneDrive? If it’s actually saved in both places there should be two copies of the file. Have you tried opening both of them?

I just found the skb file and the same error occurs when I try to open it

What about the file on OneDrive?

Maybe @colin will have some success when he has time to look at it. He usually is able to recover component definitions and materials. Once in a great while he can get the whole file.

So I guess the big question is: what causes this? It’s never happened to me before and I hope it never happens again. Are there preventative measures I can take?

Most commonly when this happens to others it’s because they are working on a file that is saved directly to the cloud and a short interruption in connection during a save or auto save results in bad data. That’s why the advice is to always work on files that are saved locally on your internal drive and only sync them to the cloud after you’ve saved and quit working on the file for the time being.

If you used your Trimble Connect cloud storage instead of One Drive, checking out the SketchUp file to work on it would first download the file to a temporary folder on your computer. Saves and auto saves would be done locally and only at the end when you Publish to your Trimble Connect storage does the file get uploaded to the cloud.

Other thing to consider is with One Drive it can sort of look like you are saving locally but you aren’t really. For example OneDrive will show up in the left pane of File Explorer like the My Documents folder and other folders on your computer.

Thanks Dave.

Just got a note from Colin that he was able to recover the whole thing. I am so grateful. He is magic.

That’s a good thing.
