+Configuration key

+| [download]
+| format = %a/%s/%n %t
+
+allows to set format for the download file pathname. Default format is
+`%f`, i.e. just filename. Other format specifiers are::
+
+ %a - author (one of if many)
+ %e - file extension
+ %f - file name in archive
+ %G - genre (one of if many), name
+ %g - genre (one of if many), title
+ %l - language
+ %n - series number (or 0)
+ %s - series
+ %t - title
+
+Format must not end in directory separator (`/` or `\\`). If specifier
+`%e` (extension) is not found in the format it is appended
+unconditionally with a dot. That is, format `%f` is equivalent to
+`%f.%e`.
