explanation for non-techies**

Imagine you have a personal assistant who helps you with your daily tasks. Now, think of Microsoft Copilot as a digital version of that assistant, designed to help you manage your work within Microsoft 365. One of the new features being developed for Microsoft Copilot is the ability to upload files directly from your computer or from OneDrive to custom engine agents.

To understand this better, consider how you might hand over a physical document to your assistant to work on or analyze. Similarly, with this new feature, you can "hand over" digital files to Copilot. Whether these files are stored on your local device or in the cloud via OneDrive, you can easily upload them to the system.

This is akin to having a filing cabinet at home and another at the office. You can access documents from either location and give them to your assistant to process. In the digital world, Copilot acts as that assistant, and the custom engine agents are like specialized departments that handle specific tasks or types of information.

By allowing files to be uploaded from multiple storage locations, this feature aims to streamline your workflow, making it easier to manage and utilize your documents without the hassle of transferring them between different systems manually. This development is part of a broader effort to enhance productivity tools, making them more flexible and integrated with the way you work.
