Mario,

linking to the folder "dropbox.com/home..." tries to open my own HOME directory. It might be easier (for us) if you posted links to individual files.

To do that, right click on a file in your dropbox folder, and a floating menu should appear. From that menu, pick :
DROPBOX > COPY DROPBOX LINK

That should be the same as copying the URL of the file. Then paste the link directly into a message, and people should be able to open the files even if they don't have a dropbox account.
