ESS OneDrive Files On Demand


ESS, formerly known as CSDS, has been working on a better way to help our customers automatically back up their files and make them more accessible. OneDrive offers a feature known as "Files On-Demand," enabling users to access all their cloud-stored files without the need to download them and occupy storage space on their device.

Enhanced Security Measures

Consumer Microsoft accounts(Personal Accounts) will not be able to sign into OneDrive or Office365 on ESS supported devices. By blocking consumer Microsoft accounts, our organization has strengthened security and ensures that only authorized accounts are used for authentication, reducing the risk of unauthorized access and potential security breaches.

What is OneDrive?

OneDrive is Microsoft’s cloud-based online storage solution. Being associated with Purdue University, everyone has access to 5TB of OneDrive Storage. Saving files to OneDrive allows you to backup your files from the computer to the cloud. You can connect any number of other devices, such as laptops, letting you keep those files in sync and making them available from anywhere.


Moving forward, you will need to sign into OneDrive. You can access your OneDrive by opening File Explorer and on the left-hand side you will see “OneDrive –”. A new folder will be created within your OneDrive called CSDSDATA. Within that folder, three new folders will be created. Desktop, Documents, and Favorites. Moving forward, if you are saving to your Desktop or Documents folder it will all be redirected to the equivalent OneDrive Folders. If you have any Favorites/bookmarks saved within Internet Explorer or Edge, these are automatically backed up to the Favorites folder. If you have already been utilizing OneDrive, your current data will NOT be affected.

How does it work?

OneDrive gives you the option to make files available while not connected to a network. There are new status icons that will help you understand your files availability.

  • White cloud with blue borders icon — Indicates the file is only available with an internet connection, and it's not using space on the hard drive. You'll need to double-click the file to finish the download and open it with an app.
  • White icon with green borders and checkmark icon — File is available offline, you can open them without an internet connection, and they're taking up local storage space on the hard drive.
  • Solid green with white checkmark icon — Indicates that you're using the "Always keep on this device" option to ensure important files are available offline.
  • Solid red with white X icon — It's an alert when there's a problem trying to sync a particular folder or file.
  • Cloud icon with arrows forming a circle — Indicates a file is currently syncing.

Files On-Demand - a feature that allows you to access your entire collection of files stored in the cloud using File Explorer without having to download them to your computer.

In other words, Files On-Demand will only download small pieces of information to make the content visible, allowing you to quickly sync hundreds of gigabytes without using space on your computer. However, you'll need an internet connection to open files that you don't explicitly make available offline, or you didn't already open.

Managing Files On-Demand

  1. One OneDrive folder
  2. Right-Click the file or folder and choose one of the options:
    • Select the Free up space option to make a file only available with an internet connection while saving hard drive space.
    • Select the Always keep on this device option to ensure the content is always available offline, but it’ll use hard drive space.
