What term is used for a folder inside your personal folder?

The term "subfolder" refers to a folder that is located within another folder, which is commonly referred to as the parent or main folder. This hierarchical structure helps in organizing files in a more efficient and manageable way, allowing users to create a clear system for categorizing their data. When you create a subfolder inside your personal folder, you are effectively creating a more specific category within the broader organizational level of your personal folder. This organization aids in quick access and retrieval of files, as users can drill down through the folder structure to find exactly what they are looking for. The concept of subfolders is fundamental in file management systems, whether on a computer or web-based file storage.
