Windows 11 won't let me open Dropbox documents that are on my hard drive (0x80070780 error)

Hi there dplam - sorry to hear you're having issues with this.

Can you please send us a screenshot of the exact error you're getting so that we can have a visual too?

Also, are those files locally available on your computer or online only? what is the desktop app's exact status and version as shown in your task bar?

Let us know more and we'll take it from there.

Glad to hear you can access your files again, dplam! If the issue resurfaces though, don’t hesitate to give us a nudge and we can investigate this further.

Again, I cannot access Dropbox files via the app on my new Dell XPS running Windows 11.  I have rebooted several times but to no avail.  To review, I got a new desktop Dell XPS a few months ago and installed the Dropbox app on it and could access all files/folders.  Over time, I began to lose access via the app to files/folders.  I can access everything if I go through the Dropbox website or via my phone and tablet apps.  I uninstalled the Dropbox app on my desktop Dell XPS and reinstalled and could access all files/folders.  Now a week or so later, I again cannot access the Dropbox files/folders via the desktop app.  What gives?  is there some setting that I need to change?  or is it Win11 that's the problem?  or????

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.

Hey dplam - does renaming or moving them out of your Dropbox folder and back in helps improve matters at all?

I have renamed and moved to my desktop.  I can open them and have been able to do so since saving them to desktop several weeks ago.

I also renamed several files and saved them in a new folder within Dropbox several weeks ago.  I continue to be able to open those files.

Almost all other files in Dropbox are not accessible to me via the Dropbox app but they are available through the Dropbox website.

What could possibly be the issue?
