TEMP Drive or Output Drive may be Full

I updated a few files from CDR12 to 16. Some open OK but I get this message with some  -

In the file details, under Properties/Details/Origin, the ones that say "Tool Version 16.0.0.1281" will open.

The files that say "Tool Version 16.0.0.999" don't.

Tried copying to other folders with no luck. What options do I have to retrieve these files?
