Unusual resource documents

in the bottom of my resources list I have some unusual files that hold many of my uploaded files as static files. I am showing them below.

I am not sure why these files are are here or what purpose they serve. Has anyone seen this practice before within Modx?

Can you show screen grabs of each of your Resource tab, Elements tab and Files tab?

I have never seen that. Maybe there is an extra or custom plugin that creates a static resource when you upload a file.

Do you have a plugin that runs on the event OnFileManagerUpload?
