You may find that you wish to share someone a large file, but you are limited by the limit for email attachments. Dropbox can easily overcome this problem by allowing you to share a download link for a file.
The quickest way this can be done is from your computer in your Dropbox folder (note this feature may be locked in the business version of Dropbox for Team Folders).
1. Right click on the file you wish to share, and then select "Copy Dropbox Link"
2. The link is copied to your clipboard and and be pasted in an email or instant message. The recipient will be able to open the link and then have an option to download the file.
