Windows 11 won't let me open Dropbox documents that are on my hard drive (0x80070780 error)
Recently bought a new Dell xps with Windows 11. I can open all Dropbox documents when going through the website but get and error message 0x80070780 when I try to open Dropbox documents that are on ...

Sorry to hear the issue’s back, dplam. Out of curiosity, if you download a couple of files from your Dropbox account online and save them to a different directory on your computer, are you able to open them?
I’d also like to know the current syncing status and app version of your Dropbox app.
Finally, can you send a screenshot of the error you’re getting, as well as one more of the files you can’t open in your Dropbox folder?

I downloaded a pdf, word doc and excel doc from the dropbox website and saved them to my desktop. I can open them. I will attempt to attach them to this reply.
I have screenshots of the error messages I get when opening each of those document types. I will attempt to attach them.
Thanks for you help.

Thanks, dplam! I’ve removed your shared links from the forum, so that your files wouldn’t be accessible. The screenshots are quite helpful, though.
It may be a long shot, but there’s something else I’d like us to check. The files you’re having trouble with, are they saved within long filepaths (that consist of more than 255 characters)?
As an example, if you had a test.txt file in your Dropbox that had the following path:
C:\Users\YourName\My Documents\Dropbox\test.txt
This file would have a path that is 47 characters long.
If this could be the case, I want you to move one of the files that currently gives you an error to the root Dropbox directory and let me know if the issue persists. The issue you're experiencing may be due to a limitation of the applications that you're using to open or save the files in question.

None of the files sent to you have a file path of 255 characters. I've got some around 70 or 90 but none approaching 255. FYI. I now cannot open any files via the Dropbox app on my desktop. It seems to start with a few files but over time blocks me from opening any of them.
