Error after open old file 3D model

[tatianal1918053]

When I open a large 3D old model, It gives me an error report. The log-file is attached. What can I do?

1. Dimesion can not open an Obj file... you need to import it to a scene
2. you did not attach any files

I know that. I'm opening a file that weighs is 7.5Gb. But that's not the problem. The problem is that with a very old version the file opened it, with the new version it no longer opens the file.

Try to export model from old Dn and import into new Dn.

There is no version before 2.3.1 😞

Part of opening an old file is converting it to the new format... With a very large Dn it sounds like you don't have any ram left over for that step

Share the Dn file please

i9-9900 processor
ram 35gb
NVIDIA GTX 1070 Ti video card

How is it possible?

I have never reopened it since I last saved it and it worked. 😞

[Ussnorway]

you would have a better idea how it happened

is it stored on a network shared drive... that is the number one cause of busted files with Windows

how can I avoid this problem on other files?
