**Pro version.** This feature is part of the Pro version of Fileshelf. What the Free version does is covered under *Free version and Pro version*.
Two ways to hand out a file on purpose: **links** that work without login and password, and **downloads by e-mail address**, where visitors get the file only after confirming their address.
## Creating a link
1. Open the download, tab **Sharing**, section **Links**.
2. Choose under *New link*: **Once** (valid for one complete download) or **Valid until a date** (7 days without a date, optionally with a maximum number of downloads).
3. Enter an address under *Send to* if you like – Fileshelf mails the link – and a note for yourself.
4. Save. The link appears **once** in the message at the top; copy it.
 The section “Links” in the tab “Sharing”.A link also works for downloads that only registered users see or that have a password. It works for this one download only. An interrupted download does not use it up. If a program fetches the file in parts (resumed download, download manager), that counts together as one download as soon as the whole file has arrived. Fileshelf stores only a fingerprint of the link – that is why it cannot be shown again later.
**Revoking:** tick the link in the list *Links of this download* and save. It stops working at once.
## Download by e-mail address
Switch on *Only for an e-mail address* in the tab **Sharing** under **Links**. Then:
1. Visitors see a form instead of the button: e-mail address, name (optional) and consent to storing it.
2. They get a mail with a confirmation link, valid for 48 hours.
3. After confirming they get the download button. It works three times within 48 hours and only for this address. Opening the confirmation mail again gives the same link with the downloads left, not a new one.
The e-mail address replaces only this one hurdle. Everything else still applies: a download in a category for registered users stays reserved for them, a password has to be entered first, a membership plan or a download limit applies with the link, too. The form appears only if the visitor could reach the download without this hurdle.
 The form on the download page.In the plugin **Fileshelf - Links** you set: the validity in hours, the number of downloads per confirmation, the address of your privacy policy (linked in the consent) and the captcha. Without a choice of its own the captcha of the global configuration applies; if none is set there, Fileshelf picks an enabled captcha plugin on its first installation. An invisible field stops automated requests as well, the same address gets at most one mail for the same download every ten minutes, and the form accepts at most five requests per hour from one visitor.
## The page “Links”
On the dashboard under **Links**: all links that still work and all confirmed addresses, with a CSV export. Because the page shows addresses, only Super Users and administrators with the permission “Configure ACL & Options” see it.
 Valid links and confirmed addresses.Edit the texts of both mails under **System → Mail Templates** (extension Fileshelf - Links). How long addresses are kept is described under *Privacy*.
