How to check file storage usage in OneDrive

IMPORTANT: New OneDrive storage capacity starting May 31st 2024


On May 31st, 2024, OneDrive storage capacity for all students, will be adjusted to 20GB, to comply with Microsoft’s new Storage quota for its educational sector clients.

If you are a McGill student, please verify your current storage using the instructions in this article: How to check file storage usage in OneDrive.

If your current storage exceeds 20GB, empty the recycle bin, remove shared items and application installers. Move older, unused files and large files such as videos, PowerPoint presentations or picture libraries, off your OneDrive, to another location right away so you are ready for May 31st storage space reduction.

The OneDrive storage provided to staff or faculty members will not be affected.

More details about this initiative can be found in this announcement on the ITS website.

Being an active student, faculty member or Staff member, you are given access to McGill's secure cloud-based file storage and sharing service OneDrive for Business. Follow the steps below to check how much space you have used.
