[error unexpected file format]

Hi, i just had the same error from an old file i worked on a couple of years ago and now its not working if anyone can help me recover the file or even let me know how to recover it would be greatly appreciated sadly this was a while ago so i dont have any skb files to recover

this is the wetransfer link for the file any help would be greatly appreciated

About half of the data in the file is missing. I don’t think it can be recovered. Have you tried the backup (.skp) file? Were you saving directly to a cloud location?

Hi, i tried to find the backup but sadly this file was last worked on like 3 or 4 years ago and i couldnt find any. No it wasnt being saved to a cloud location. thank you for trying though

I can’t open SketchUp files. As soon as the welcome page appears and I try to open any file, the application immediately shuts down.

You have sent in various bugsplats, a couple of which relate to an issue that can happen 28 days after you last signed in.

Can you try opening each version of SketchUp you have, and sign in and out? Start with the oldest version. When you get to SketchUp 2025, after signing out, sign in again, and then see if files open ok.

I did, but unfortunately I still cant’ use the program

Hello,
I’m encountering the same issue when trying to open one of my SketchUp files. I’m using SketchUp Pro 2018, and each time I attempt to open the file, I receive this error message:

“Format de fichier inattendu.”
(Unexpected file format)

Here is the link of my file https://drive.google.com/file/d/1YNThVcuRBOYZNkrDg7NGsfAVACWA0YJJ/view?usp=sharing

Please help me;

The file is missing a lot of data. It’s missing in little chunks scattered throughout the file. Nearly half the file is trash. Looks like nothing to recover.

Where were you saving the file while working on it? Are you using a cr acked version of SketchUp 2018? Do you have the .skb backup copy? Can you rename it to .skp and open that?

Thanks for your answer. I saved the file locally Drive, and unfortunately there’s no .skb backup in the folder. Thanks for your help.

Why is that. Did you turn that capability off or is it due to a bad cr acked version?

I turned it off, The file was fine and the work was nearly complete, but it crashed and became corrupted. The file size is not zero, however.

That’s unfortunate.

No. It’s not zero but it’s missing too much data to be a viable SketchUp file. No point wasting more time on it now. If you need the model you’ll have to start over.
