FileSender is a web based application that allows authenticated users to securely and easily send arbitrarily large files to other users. Authentication of users is provided through SimpleSAMLphp, supporting SAML2, LDAP and RADIUS and more. Users without an account can be sent an upload voucher by an authenticated user. FileSender is developed to the requirements of the higher education and research community.
The purpose of the software is to send a large file to someone, have that file available for download for a certain number of downloads and/or a certain amount of time, and after that automatically delete the file. The software is not intended as a permanent file publishing platform.

Which version should you choose
There are 3 releases, of which 2 are maintained:
- Version 1 is an archived, older version of FileSender which is not maintained
- Version 2 is the current mainstream version with active feature developmet
- Version 3 is in development, with alpha releases. This version features a new UI
Version 3 and Version 2 should have the same functionality but version 3 uses Bootstrap to present a more modern UI. The uploaded files storage handling is the same in version 2 and version 3. The database schema is very similar between the two and should be identical at specific release. For example, version 3.0alpha2 explicitly mentions that it is feature compatible with 2.30. So you should be able to direct 3.0alpha2 at the same uploaded files and database and have the system function.
The version 2.x series is the recommended choice in late 2021. Perhaps in 2022 version 3.x will become the recommended choice. The latest version can be obtained from the github releases page.
The release numbering for the 2.x series follows the pattern 2.1, 2.2, 2.30 etc. Each of these releases builds on version 2.0 adding bugfixes and features. Each new release in the 2.x series will describe if database updates are needed (most often by running a script) and if web page templates have been updated in case you customize those on your site. If is intended that you can migrate an active site to new releases with very minimal downtime.
The 1.6.x series is considered deprecated. It is still available for those who have not upgraded to a 2.x installation: 1.6.1, released on December 30th 2015.
As of late 2021 the documentation for FileSender 3.x is the same as that of the 2.x series. The same options are available in both versions of FileSender and setup and configuration is the same. Both FileSender 2.x and 3.x also share the same database schema and you should be able to migrate a version from 2.x to 3.x retaining active file uploads and all the information in the database.
Perhaps in 2022 FileSender 3.x will become the major release at which point the documentation for 2.x will be cloned to a 3.x series.
Please see the documentation for versions 2.x.
FileSender is released under the BSD license. It is open source software and available for free.
