autogenerating ".uuid" files in linux directory

I downloaded fonts from a website (that seemed legitimate to me) and transferred the contents to /usr/share/fonts/directory. There's a .uuid file being generated for every directory with a string like this as its sole content:

f25e9432-c6f1-4bbe-a33c-89289a8d17f1

This file regenerates right after I delete it. Is this a malicious program? Is this indexing by the OS itself or is it something like fc-cache running in the background? What could be the cause of this?

This has nothing to do with the fact that you've downloaded your own fonts. This is simply just fontconfigdoing it's job. It very well could just be the cached data created. Only rather, the binary data is being converted into a uuid string/unique ID.

So, I would say no. I do not believe this to be the cause of anything malicious. Nor are any of these occurrences a result from you downloading fonts from your web browser.
