If your instructor allows file uploads as a submission type, you can upload a file from your computer as an assignment submission.
Any attachments added as part of a graded assignment submission are also copied to your user files but are not counted against your user quota. However, once the file has been uploaded as a submission, you cannot delete the file. Files are stored in the Submissions folder.
If your institution has enabled Google Docs as a submission type, you can also upload a file from Google Drive.
To upload a file from your computer, click the Choose File button . When the file window appears, locate and click the name of the file. At the bottom of the window, click the Choose or Browse button (depending on your browser).
To upload a file you already uploaded to Canvas, click the Click here to find a file... link . The file list will expand. Click the name of the file.
If you have access to upload a file from Google Drive, you can submit a Google file by clicking the Google Doc tab .
