Editing Template:File category check/doc

== Explanation ==
Files should always be in at least one of [[:Category:Images]], [[:Category:Videos]] or [[:Category:Sounds]]. Usually [[Special:UncategorizedFiles]] should be sufficient to detect them but templates like [[Template:Biotech]] add the files to other kinds of categories. To files that are categorized but lack a file category an inline query isn't enough, but can be done in combination with this template. 

== Code ==
The following can be used to systematically scan all files in badges of 500 (upper limit):
<pre>
{{#ask: [[File:+]] [[Modification date::>10 December 2022 01:53:28]]
 | limit = 500 | format = template | template = File category check | link = none
 | named args = yes
 | ? = file
 | ?Modification date = Date
 | sort = Modification date
 | offset = 0
}}

The last checked file has a ''Modification date'' of: {{#var:date}}
</pre>


== Output ==
If there are no files below this text, there are no files that are not in a file category.

{{#ask: [[File:+]] [[Modification date::>10 December 2022 01:53:28]]
 | limit = 500 | format = template | template = File category check | link = none
 | named args = yes
 | ? = file
 | ?Modification date = Date
 | sort = Modification date
 | offset = 0
}}

The last checked file has a ''Modification date'' of: {{#var:date}}
