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?

    There must be some sort of permission or third party issue on the OS profile you're working on at the moment dplam 

     

    Can you try creating a new OS profile and installing the desktop app there? 

     

    Let me know if you still get the same error.
