ERROR: 0X80070780 File cannot be opened by the system

Greetings,

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"

Thank you very much, Dan

Hi @danens1863,

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.

Good luck.
