R SketchUp model file got corrupted or wasn’t properly saved before my Windows laptop glitched

Technical Problems SketchUp for Web

I was working on a SketchUp model and usually save my files on an external hard drive I plug into my laptop. Normally, it saves without any problems, but this time my Windows laptop wasn’t working properly, and I think it didn’t save the file correctly. Now I’ve lost the SketchUp file I was working on. Every time I try to open it, I get a message saying, “The file does not appear to be a SketchUp model,” even though it is a SketchUp file. I noticed that the latest time I worked on it still appears in the %temp% folder. Is there anything I can do to recover it?

The file you posted doesn’t look like a SketchUp file. Looking at the contents in a hex editor, it doesn’t have the customary SketchUp file header. Did you use some disk recovery software to produce it? I don’t know if Colin has better luck figuring out what data is missing.

Do you have the backup (.skb) file? You could try opening that (rename a copy of the file with the .skp file extension and try opening). That would have all the file excepting your last work session.

I see the same thing as @Anssi reports. The file you shared might have been a SketchUp file but it isn’t now.

This kind of thing has been a problem for many users. Best practice is to save to an internal drive. Copy the file to an external drive if you must.

Your profile says you have a Studio subscription which means you would have unlimited storage at Trimble Connect. Were you also saving your model there?

Is there anything we can do to recover this file? If not, I’ll be losing a significant amount of work I’ve done. I already tried renaming and opening the backup (.skb) file, but it still says does not appear to be a sketchup model

I already tried renaming and opening the backup (.skb) file, but it still says does not appear to be a sketchup model. I did not save the model at Trimble Connect

It would appear too much of the file is damaged to be recoverable.

That’s unfortunate. If you had been doing so you would have backups for every time you saved to Trimble Connect which would at least mean you’d have less work to do to get back to where you were.

Going forward, save your model to the internal drive on your computer and also save to Trimble Connect.
