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
I was able to fix this -- you have to uninstall (reboot) and then re-install dropbox. That re-installed all the permission stuff and got it working. Sadly there is no 'repair' option and I just went right for uninstall/reinstall.
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.

The problem is related to credentials. Dropbox app in Windows uses onedrive to create a virtual drive. You want to be sure that you are logged into onedrive with credentials that grant you access to the windows local drives or Adobe apps you expect to use.
Best to uninstall and reinstall the dropbox app, and it should reset credentials. Worked for me.
I can see this error as well. It has corrupted all my photos which is causing now a very painful process. Thank god I have a cold back up - I dont think I will use Dropbox for photo any longer. Its just very poor management and user experience.
I also have not been able to fix it and I dont want to involve Microsoft windows or any other software, I bought drobox because I want to use that one application - not be forced to use others.

Hey Roger H.15, hope it’s OK if I jump in!
Would it be possible to provide a screenshot of any errors you keep receiving when trying to open your files?
Also, does this happen specifically for files that are set as Online-only or for local ones, too?
Let me know!Nancy Thanks for your response. It seems to be a problem when I view photos on my PC (Dell Laptop running windows 10 and link to dropbox. When I go into dropbox directly thankfully all photos are there.
and
any advice or assistance would really be appreciated. Not sure what triggered this corruption, It could have been a recent windows upgrade, as they used to work for many years very nicely.
