The frequency of the following error is occurring more and more:
ERROR: 0X80070780 File cannot be opened by the system
Trying to open several PDFs and it says it is impossible to do. It feels like the I am working off a corrupted hard drive. This strikes at the heart and soul of using Dropbox as it quickly leads to the conclusion that Dropbox "Cannot Be Trusted".
Cannot see anything I am doing wrong. Help would be "Much, Much Apreciated"
I agree with you, that many new "features" of Dropbox look like bugs. According your description, seems you are disturbing by a bug with name "Smart Sync". Very poorly implemented and as a result such issues come up. If you can, turn this feature (bug) off. If you need to save disk space, considered "Selective Sync". As a last resort (you can't live without "Smart Sync") make sure the files you are working on are set 'local' in advance. 🤷 That's all you can do with Dropbox right now.
