I know there probably is not a limit, but I am more asking if there is a good reason to avoid putting a lot of items in a folder. I am about to create hundreds of thousands of documents that will act as placeholders for my company's assets. Users will then add relations from documents to these placeholders. Should I artificially break up these items over many folders or is there an harm in putting them all in one folder? Users won't be navigating this folder, but rather searching for these documents when creating relations.

Thanks.
