Problem: new overleaf project using new template (so no copying the project through interface->copy). The projects have separate folders with multiple files inside, mostly images.

Previously I discovered that you can import files from another overleaf project, without having to download/upload them individually, but I’m still unsure about how linked they are and what happens if they get deleted from the original project.

Today I discovered a better way: download the overleaf project zip, unzip locally, then drag and drop the (multiple!) files to a newly created folder in the new project, all together.
