Files available for download can be valuable assets, and as such it can be advantageous to track downloads with in-depth analytics. This can be accomplished by providing a gateway step before file download to ask for an anonymous user's e-mail address and/or other information. Once the anonymous user's response is validated, the file becomes available through a direct download or a link on a secure page.
A number of file management modules implement a solution similar to this, and what follows is a chart comparing them to one another.
|Name||D7||D6||File Field support||Configurable fields||Collects e-mail addresses||Download link in e-mail||Downloadable statistics|
|File Download Form||Planned|
|Webform Protected Downloads||1||2|
|Webform Private File Gateway||Planned||Track da files|
1 Available in the Drupal 7 version of the module.
2 No direct download link, but a link to a protected downloads page is available.
