Corrupted skb AND skp files - need to retrieve them asap!

Hi there !

I have a problem with a bunch of corrupted files. 4 different projects were corrupted, as well as their skb backup files. When trying to open them, I get the message that this file does not appear to be a sketchup file. I have tried EVERYTHING I could find online. Changing the skb in skp for the back up file, importing instead of opening, trying Sketchup web, opening them in Sketchup Viewer…That last one brought 2 of the 4 projects back to life, but I`m left with 2 projects impossible to open (of course the 2 most important ones !).

My only hope comes from the fact that both files are still 4.02Mb and not 00.00…so there must be something salvageable ? Can anyone help ?

If you can reply with the files, we can see what can be recovered.

Were you also saving backups of the files to your Trimble Connect storage?

No, unfortunately. Would be too easy ! haha…

Here is the skp : https://drive.google.com/file/d/1hn_Oc2MFKYV0NK8sFPE5aZWaAR8ynyH5/view?usp=drive_link

And here is the matching skb : https://drive.google.com/file/d/1eqJM_0O4A0C1qiYaOC3ZMkal9qKQkLsM/view?usp=drive_link

I tried reading the Hex code of both files, and it seems the beginning of the skb and the end of the skp were was not corrupted, but I could not see the Sketchup header in any of them, and lots of lines are missing between the two. Any time spent on our project is deeply appreciated ! And we learned from our lesson, we are now the happy owner of 5 differents save of each projects that came back to life, in 5 different locations…

The SKP opens ok in SketchUp 2026. It may be that we fixed something recently. See if this opens for you.
