Error moving file: This is not a supported operation

Explorer | Level 4

I’m a Dropbox Plus account user and I have the Dropbox desktop application installed on my Mac. I have a folder called 'Archive' which uses Smart Sync, so all its contents are online-only.

When I drag and drop a folder full of files to the application (from an external hard drive), I get an error message saying, 'Error moving file: This is not a supported operation'. But then I click OK and the folder and files get copied over anyway and get a green checkmark. Then I right-click the folder and select 'Smart Sync > Online only' and it Smart Syncs as expected.

Is this just because the app is warning me that it cannot assign these new files as online-only until it syncs from the local drive first? If so, maybe the modal should just say that instead of making it seem like the files won't copy over at all (which they do)?

Is this message from the Dropbox app, or your operating system? Post a screenshot of the error if you can, excluding any private information.

Looks like it may be a system alert, though it's tagged with a Dropbox icon. So I don't know what's generating the warning.

Hey there @garyhorsman, thanks for the screenshot, definitely provides a better understanding of the behavior. 

From what I can see, you're copying the folder into the Dropbox desktop app.

Could you please try pasting it into the Dropbox folder via Finder and let me know if you also get the same error message?

Let me know what you find!

I right-clicked a folder on my external drive, selected 'copy', then switched to the Dropbox desktop app window, right-clicked just under the list of files in the directory where I wanted to move the files and selected 'paste' and there was no error message. The menu bar icon shows the circling arrows, indicating the files are uploading.

So I guess that does help avoid getting the error message.

I haven't had any trouble using the regular Finder folder nor the browser-based version.

Good tip, @Lusil. I think what I did was slightly different from what you suggested, but it did work. I appreciate your help slightly smiling face

Hey @Lusil I see the workaround you suggested does work. But it's unfortunate that the Dropbox experience on Mac is now mostly funneled through this app. So it seems extremely inconvenient to have this well designed looking app, with terrible copying functionality. I mean if we as users get an "Error / Alert" each time we drag and drop files into the app to sync, doesn't that defeat the purpose of the app altogether??

Hey @dolphinjosh, thanks for nudging us on the thread and for your feedback!

I'd be more than happy to help look into this with you.

As a first step, could you clarify for me if you're getting the exact same error message? Are you trying to drag-and-drop folders/files into the desktop app or copy-paste?

Also, I wanted to mention that if you'd like to use Finder to navigate through your Dropbox folder, you can do so by changing your preferences. More specifically:

  1. Click the Dropbox icon in your menu bar
  2. Go to your profile picture or initials in the upper right corner.
  3. Click Preferences….
  4. Select the dropdown next to Open folders in:
  5. Choose Finder.

In any case, let me know what you find! grinning face with smiling eyes

I am having this same issue. Trying to copy a large folder of photography from an external hard drive to a new dropbox folder. I tried to pull it and copy it from the finder window but It won't work. Please advise. This is the first time I have encountered this issue.

Hey @domphipps101, thanks for checking in with us and sorry to hear that you're having trouble copying content in to your Dropbox account. 

Could you please clarify a few more details, such as:

  • Are you using your Finder or the desktop app? 
  • Have you tried copy-pasting or are you dragging the folder?
  • Does this happen with a specific folder/file?

Keep me posted!
