Microsoft OneDrive for ECS Students

In the upcoming fall semester, our ECS cloud server ( and Voyager-temp will become read only, and will eventually be decommissioned. They will still be accessible via existing ECS accounts. They will be replaced by by Microsoft Onedrive. Right now, all ECS Students, Faculty, and Staff can use their CSUS Saclink accounts with Microsoft Onedrive. The better integration and the much larger amount of space will hopefully be a huge upgrade for ECS students, clubs, and faculty trying to share and store large project files, videos, etc. Onedrive is a cloud storage service offered by Microsoft, similar to Dropbox or Google Drive.

Benefits of Onedrive

  • Every account has 1TB of space compared to 10GB with our current cloud storage system.
  • Integrated sharing and management options via the right-click menu in Windows Explorer. Share with another CSUS account by simply looking up their name.
  • Files are only synced to your local system on-demand, preserving your local hard drive space - though you can choose to keep specific files local so that OneDrive doesn't transfer those files every time you log in.
  • Version History: Ever deleted a large piece of code or paragraphs of an essay and regretted it? Onedrive keeps a version history of your files (as well as deleted files) which you can restore without needing to ask ECS computing services to restore your files.
  • We recommend using onedrive for storing large project files or older homework assignments that you may want to keep but don't necessarily need right now. For files that you are actively working on as part of projects and assignments, we recommend storing those in your U-drive (10GB), space permitting. This will get around the need to download them locally every time you need them. Of course, you can always back up your work to your OneDrive at intervals to take advantage of the versioning.

How to Use

Logging In

Type "OneDrive" in the Windows Start Menu Search. Use your CSUS credentials to log in (e.g.


Once you've logged in, the system should sync your OneDrive folder and you should see it in Windows File Explorer. In order to share a file with someone, right click on a file and select "Share" from the context menu. You can look up other CSUS users by name, or simply copy the share link to send via an email, text, etc.

Access on lab machines

OneDrive should be installed on all ECS lab systems. It should also be built into Windows 10 on your personal machines, unless you have uninstalled or disabled it. If you need to re-install it, please visit the official Microsoft OneDrive website.

Keep a Local Copy

if you'd like to keep a local copy of a file, which may be valuable on systems with slower internet connections, you can right click and choose "Always keep on this device". The icon will turn solid green to indicate success. Use the same right-click menu and select "free up space" to undo this option. To preserve your system's hard drive space OneDrive files are available, but not downloaded, until you need them. Keeping a local copy will download it and keep it on the local system until you choose to stop storing it locally. Be aware of space issues when storing local copies; although your OneDrive has 1000GB of space, you may be limited by the size of your system's hard drive.

What's Being Shared with Me?

If you'd like to see a list of files and folders that someone has shared with you, use the "View Online" option by clicking on the cloud icon in the Windows System Tray. This will take you to Microsoft OneDrive's web interface, where you can see and manage files in more detail.
