The My Files folder creates folders based on default events in Canvas. Once you upload a file related to one of these areas, the folder and accompanying file will be created for you.
- The Conversation attachments folder  stores files that you attach to Conversations messages.
- If your institution enables you to upload a profile picture, the Profile pictures folder  stores photos that you have uploaded as a profile picture.
- The Submissions folder  contains copies of your assignment submissions; assignments are organized by course folder and displayed alphabetically.
- The Unfiled folder  stores files that you attach to discussion topics or discussion replies (if attachments are allowed by your instructor).
My Files also includes any additional folders you create to organize your files, as well as any files not uploaded to a specific folder. Any files in the My Files folder that are not related to assignment submissions count toward your user quota.
Note: For assignment submissions, if you submit a file that you've previously uploaded, you can delete the previously uploaded file after it has been submitted and free up extra storage in your user files.
