Not able to see Downloaded mods in content editor


I’ve been making some stuff in the content editor, but recently i found a great mod that i downloaded and wanted to edit. When i click the open an existing mod i cant find them in the folders, they are just empty?

I have tried changing name to match what it is looking for but that makes me unable to open them? arent u aloud to open and edit others mod or what is the issue?

Thanks for the help!
