Fail to open document

I cant open my document on sketchup its around 200 mb.

Are you really using the free web version as your profile indicates? What operating system? 2023 does not answer that question. What graphics card? “4” is not a graphics card. Putting the correct information in your profile is important if you want help.

Maybe @colin will be able to do something with it?

Half of the file is filled with zeros. Only real hope is if there is an SKB file in the same folder.

After I’ve been working in the model without problem, suddenly I can’t open it.
Is there anyway to recover it?
Thanks in advance
Please, find attached the file into this link.

Both files are almost completely filled with zeros.

Thanks anyway Colin
