SendLink allows you to share either individual files or entire folder hierarchies using tiny links that you email to the people you want to share with. A recipient of your file-sharing email simply clicks on a link to start downloading. If you have sent them a file link, the file download begins immediately. If you have sent them a folder link, they will download a folder index to their Web browser. This folder index contains an up-to-date list of the files and subfolders that may be accessed from that folder.
