I had noticed that, thanks. I added that to the bug report.
Short version is, that problem fixing was changed in some way with 2021, and something that was being fixed ok in 2020 and earlier, was no longer being fixed. For anyone coming here with a file that won’t open in 2021 or later, opening it in 2020 would be worth a try.
Hola, soy nueva en la comunidad y llegué acá buscando la frase “formato de archivo inesperado” que aparece cuando intento abrir un archivo que tiene un proyecto que aún no fue visto por el cliente.
Encontré la manera… gracias b.superal por explicar cómo lo pudiste hacer!!
The developer looked at the file. It seems to have been made with the first version of SketchUp 2021, and that did have some file saving issues that we quickly fixed. There is no hope for this file, but if you are still using 2021 you should update it to the current version.
You can get the latest 2021 installer from this page:
So far as I can see, that file doesn’t show the typical effects of mangling from saving to somewhere other than the local hard drive. But I can’t open it either. Perhaps @colin can do more, or pass it to a developer who can assess what is wrong.
The scene is empty, but this recovered file is nearly as big as the original, which suggests that you used components that included large areas of the model. See if you recognize any of the components, and place them in the scene.
I have recovered 35 Sketchup files, some of which I can open as normal while the rest prompt the error “Unexpected file format” or “Failed to open document”. I have recovered the files from a corrupted external hard drive and would like to know if the files are still recoverable as they’re extremely important to me. If you could help me figure this out I would really appreciate it. Three of the 35 files are in the Wetransfer link below.
