Sync documents between iCloud and DEV

Thank for taking time for my problem.
Example :

1 - I download a new PDF on my computer
2 - I move this PDF directly on the DT interface in the right folder.

Before, in the same time the document was moved in the right folder on my computer (Means iCloud in my case).

But today, the document is well referenced in the DT database BUT he is not moved in the right folder on my Mac (iCloud)

Hope I have been clear enough

regards
