To save a copy of the entire project, follow these steps. First, ensure all files and documents related to the project are organized in a single folder. Next, create a backup by making a copy of the folder and storing it in a secure location, such as an external hard drive or cloud storage. This ensures that even if something happens to the original project files, you have a protected copy that can be easily retrieved when needed. Remember to update the backup periodically to include any new changes or additions to the project.
