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 my hard drive.  That error message is "the file cannot be accessed by the system".  The Windows community says that it could be due to corrupted windows files but I ran all of the DISM diagnostics and found no corruption.  It said that it could also be due to not having administrator powers but I confirmed that I am the administrator and logged into that function.  I can access the files through the Dropbox app on my phone and tablet. What can I do to be able to access the Dropbox files located on my hard drive?

    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.

      I have now uninstalled and then reinstalled Dropbox on my desktop. I now have full access to all files. However, I did this a couple of weeks ago and over time I stopped having access to some files.

        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.

    for anyone having problems with windows 11 make sure you right click the Dropbox icon within windows explorer and choose "Make available offline"

      Thanks but when I right click on the Dropbox icon in windows explorer, I don't get that option.  The pop out menu does not show a Dropbox icon.

        Have you checked Drobox is running on your machine? May be worth a redownload and install: www.dropbox.com/downloading

    Hi, I'm receiving the same exact error on  Win 10 PC. My use case is another user had DropBox, and had >90 GB of files in their C:\users\dropbox   folder. File thumbnails show up with an X in the lower left hand corner. I have reset NTFS permissions to everyone\full control, disabled inheritance, applied to sub-folders. I uninstalled and reinstalled DropBox desktop App, still no access. I'm an IT Pro with a decade plus of experience, so can provide additional technical details if necessary.

      Hi schnugee, is this a grey X you're seeing as the sync icon? Do you have OneDrive currently installed and running on your machine?

        Thank you for the response Jay. I see no indications from the Registry that OneDrive was enabled, or used by this user.
