Opening old Rhino files

Rhino Rhino for Windows
1

Hi,

I have to update something I did many years ago. I have located the Rhino files, but when I try to open them I get the error message " xxx.3dm is not a Rhino m-archive". They are 3dm files probably 15 years old at least. I guess it is not impossible they got corrupted (they have moved computer several times but always on Windows) but I hope they are OK and useable otherwise I have a fair bit of work ahead of me…

Many thanks for any guidance

Jack

Hi Jack -

That does sound like the file got corrupted, I’m afraid. What does Audit3dmFilesay?

A million apologies for the delay,

Yes, found other corrupted files (jpgs and Docs) in the same folder that had been backed up years ago from an old computer … So. I will let them all rest in peace…

Best

Jack
