Files or folders in your Dropbox folder can be shared, instantly. All you have to do is select the file and then select Share link from the Dropbox menu. Once you do, you can send the link to anyone over email, IM, text message...you name it. Friends who click the link will get an instant preview of the file or folder through their browser.
Note: If you share a link to a video, the recipient will be able to watch up to 15 minutes of it on the preview page on the Dropbox website. For a longer video, the recipient will need to download the file or watch from the Dropbox mobile app to see all of it.
Once the link is created, a preview window appears. Enter the email addresses of the people you'd like to send the link to or select Get link to copy the URL so that you can paste it in your email, instant message, etc. This preview page is also what others will see when they use your link.
You can remove a link from the Links tab on the sidebar of the Dropbox website or by selecting Remove link from the gear menu that appears when the link creator (you) use the link.
Your links are secure! When you get a link, Dropbox creates a unique token used only in that link. It is almost impossible to guess the token, but even if someone was able to, they'd have to know the name of the folder and files the link points to. That said, if you publish the link on a website or somewhere public, anybody can use the link and the website where your link is posted might even be included in search engines.
Also note, when you choose to create a link to a folder, everything in the folder and its sub-folders will be accessible from the link. Move items out of the folder or remove the link if you no longer wish to make these files accessible from a link.

You should only use shareable links for files that you have the legal right to share with others (for example, documents, photos, software, music, and videos that you personally created). You do not have the right to share files unless you own the copyright in them or have been given permission by the copyright owner to share them. Purchasing or legally acquiring video, music, ebooks, or software does not give you the right to share that material with third parties over the Internet.
If you have any doubts about whether you have the legal right to share certain files, you should not share them. You represent that files shared using shareable links do not violate Dropbox’s Terms of Service and that you own all copyrights to them or have been given permission by the copyright owner to share them. Dropbox has adopted a policy of terminating the accounts of users who repeatedly infringe copyright or whose accounts are subject to multiple infringement allegations. If you repeatedly share files that infringe others’ copyrights, your account will be terminated.
