A "Duplicate" or "Copy" refers to an exact reproduction of an original item, document, or file. This can apply to various contexts, such as printed materials, digital files, or even physical objects. Duplicates are often created for backup purposes, sharing information, or preserving important data. In the digital world, creating a duplicate file is a common practice. For instance, when using software like Microsoft Word or Google Docs, users can easily make copies of their documents to ensure they have a backup or to share with others. Duplicates help maintain organization and prevent data loss.
