Hi there

How does one download a shared file (public visibility) from dropbox? I used to use the following code to achieve the task, but I suspect that dropbox has changed something because now it doesnt work as before:

outfilename = websave(filename,'https://www.dropbox.com/s/y0v5z3rtbw15kwb/OOT_Example_data_DONOTDELETE.zip?dl=0');

where the file "https://www.dropbox.com/s/y0v5z3rtbw15kwb/OOT_Example_data_DONOTDELETE.zip?dl=0" is a 43mb zip file. From matlab it downloads only 330kb of the file but in a webbrowser it downloads the whole thing. Can anyone help me?

Thanks in advance!

Cheers

Jakob

For me using ?dl=1 instead of ?dl=0 did the trick.

That's curious, but it sure does fix the problem. Thank you so much for your help!

If you try both links in a browser, you can see that dl=1 activates the download immediately, while dl=0 shows you a page that asks for confirmation. Which Matlab can then dutifully write to a nonsense file of 300 kb.
