Hazel attempting to process incomplete Safari downloads

Hello and first allow me to say how awesome Hazel is, it's one of the reasons I made the shift to Mac from Windows and boy I'd never want to get back

I am encountering consistently the following problem: I have a rule that recognizes downloaded files from a given website and moves them to my NAS. These are reasonably large downloads, so they take a moment to download.
When I have Hazel watch my Downloads folder, everything works fine, the app waits for the download to complete and then moves the file away.
However, when I apply the same rule on an Action folder in my Dropbox, it consistently fails: Hazel sees the incomplete download and moves it out of the way (incomplete) and Safari then complains that the file can't be written (obviously).

However, I read on the forum that Hazel wasn't supposed to process incomplete downloads. Am I doing something wrong? Is it because these are large files? Is there a workaround other than putting a delay in the application of the rule?

Thanks!

How is Safari downloading to that folder? Did you re-set it's download folder to that folder?

No, Safari's download folder remains the default Downloads folder. However I'm having Safari ask me where to save a file every time I download something.

Ah, I see. Currently, Hazel only recognizes Safari downloads in Safari's downloads folder. I'll have to change things to look for those everywhere. Just to double-check, the incomplete downloads still have a .downloads extension, right?

In the meantime, you can add a condition to filter out files with .downloads. You can add a rule at the top of the list like "Extension is download, Ignore file".

Thank you very much Mr. Noodle! This had eluded me. I confirm, Safari downloads indeed have a .download extension (just tried it again tonight). I will filter them out when needed
