All files will be read by PHP - therefore the directory might be protected against direct web access. This is the

The user typically expects meaningful and distinct file names for different download links.
+* mode `persistent link` (s:0) - *download*: `d:[<path/name>]<key1>[/<keyN>]`
+
+ This setup is divided in part a) and b):
+
+ Part a) - offering the download link.
+
+ * The whole part a) is optional. The download itself will work without it.
+
+ * (Optional) *path/name* = of the QFQ `download.php` script. By default``typo3conf/ext/qfq/Classes/Api/download.php``.
+ Three further possibilities: ``dl.php`` or ``dl2.php`` or ``dl3.php`` (see below).
+
+ * *key1* = give a uniq identifier to select the wished record.
+
+ Part b) - process the download
+
+ * In the QFQ extension config: File > Query for direct download mode: `download.php` or `dl.php` or `dl2.php` or `dl3.php`
+ up to 4 different SQL statements can be given with the regular QFQ download link syntax (skip the visual elements
+ like button, text, glyph icon, question,...)::
+
+ SELECT CONCAT('d|F:', n.pathFileName) FROM Note AS n WHERE n.id=?
+
+ All `?` in the SQL statement will be replaced by the specified parameter. If there are more `?` than parameter,
+ the last parameter will be reused for all pending `?`.
+
+ E.g. ``10.sql = SELECT 'd:1234|t:File.pdf' AS _link`` creates a link
+ ``<a href="typo3conf/ext/qfq/Classes/Api/download.php/1234"><span class="btn btn-default">File.pdf</span></span>``.
+ If the user clicks on the link, QFQ will extract the `1234` argument and via ``download.php`` the query (defined in
+ the Typo QFQ extension config) will be prepared and fires ``SELECT CONCAT('d|F:', n.pathFileName, '|t:File.pdf') FROM Note AS n WHERE n.id=1234``.
+ The download of the file, specified by ``n.pathFileName``, will start.
+
+ If no record ist selected, a custom error will be shown. If the query selectes more than one record, a general error will be shown.
+
+ If one of ``dl.php`` or ``dl2.php`` or ``dl3.php`` should be used, please initially create the symlink(s), e.g. in the
+ application directory (same level as typo3conf) ``ln -s typo3conf/ext/qfq/Classes/Api/download.php dl.php`` (or dl2.ph, dl3.php).
+
+ Speaking URL)
+
+ Instead of using a numeric value reference key, also a text can be used. Always take care that exactly one record is
+ selected. The key is transferred by URL therefore untrusted: The sanitize class :ref:`alnumx<sanitize-class>` is applied.
+ Example::
+
+ Query: SELECT CONCAT('d|F:', n.pathFileName) FROM Person AS p WHERE p.name=? AND p.firstName=? AND p.publish='yes'
+ Link: https://example.com/dl.php/doe/john
