Dropbox removed its Public Folder.
So now, you may find yourself trying to download Capx files (or even view images) or anything that were shared through the public folder of dropbox and end up with a 404 error, file not found.
Some of those files will likely be lost for good.
For others, it is likely possible to get them by asking them to their author, if he/she's still active in the forums.
The best thing to do is to post in the topic where you have found a file you want to download.
In your post, make sure to alert the person who posted the original file using 
nickname (with the proper capital letters and proper name, otherwise the alert won't work).
Let them know the URL of the post they posted the capx in and ask them nicely if they can post it again using another service or share it some other way.
Tip by shinkan:
Normally when you want to share a file you'll get a link similar to this:
https://www.dropbox.com/s/n78c9dywrulcz ... .capx?dl=0 (some random link from the forum)
So when you click on it new dropbox page will open where you can sign in, download file etc etc... it's just to many clicks...
Instead all you need to do is to change the last dl=0 to dl=1. So the link looks like this:
https://www.dropbox.com/s/n78c9dywrulcz ... .capx?dl=1
Then when you click on it download will start immediately without annoying new pages, clicks, confirmations etc.
So, yeah that's it. Little tip to speed things up <img src="{SMILIES_PATH}/icon_e_smile.gif" alt=":)" title="Smile">
Best regards and take care!
Tip by Ethan:
add ?raw=1 to have images appear in the post rather than an link to the image.
example
