Asset storage location local server Win 10

Hi.

Where are assets stored when they are uploaded to my local server?

Are they simply referenced from the original upload path, or are they duplicated?

This is important because if they are referenced from original path, and I move the file, then it will break.

I’d also like to change the storage path for local server assets, so in the event they are stored on my tiny SSD boot drive, it isn’t filled up with assets.

I don’t understand a lot of how this server side of things works yet to be honest. Explanation would be gratefully received.

Thanks.
