Whenever you right click on a file or folder in Dropbox, and choose “Share”, you will generally get a link which looks like this:
Ever wondered what “dl=0” stands for? It’s download, and it’s set, as a default not to download your file.
Just change dl=0 to dl=1 and the file will automatically start downloading whenever the recipient of the link clicks on it.
There are a lot of storage solutions these days, but I prefer Dropbox for better integration with other services, like ifttt.com.
