I am very new to Craft and how it works. I've got a client with a Craft site (v2.9.2), that I help them with. It was created by another developer.
I want to help them tidy up their Assets.
There are two folders (on S3) for their Assets. /Media and /Media/Files.
Scanning by eye, I can see /Media/Files appears to be a subset of what's in Media (meaning, they are duplicate files). Before we potentially delete the /Media/Files folder, I'd like to programatically confirm if any of them are being used. My suspicion is only files in /Media/ are used on the site.
Is there any easy way to see which assets are in use, and where they are used?
I found questions on StackExchange re how to see what media is not in use, such as this one. I also found a question on how to do something similar to what I need.
Although, to be honest, I had no idea where I'd utilise such code. I'm not going to get into creating a new plug-in.
For example, this was shared in the answer to that question:
{% set content = craft.entries.section('content').find() %}
{% set usedFotos = craft.assets.relatedTo(content).order('filename').find() %}
{# Loop throught the array of assets #}
{% for usedFoto in usedFotos %}
<h2>{{ usedFoto.filename }}</h2>
<ul>
{# Loop throught entries related to this asset #}
{% for entry in craft.entries.relatedTo(usedFoto).order('title') %}
<li>{{ entry.title }}</li>
{% endfor %}
</ul>
{% endfor %}
Where would I utilise this code?
