Regarding creating new folders: second-level and third-level folders.

Hello, my team is facing a huge problem with project file categorization, such as folders like Project 1, 2, 3, and so on. Each folder contains many version files. I would like to create new parent folders (which already exist), second-level, third-level, and even fourth-level folders to store my sub-files, so that my team can better organize the files.
