If you are adding a file to a module, you can upload a new file by clicking the New File(s) link [1]. Uploaded files are automatically published and also display in Course Files.
To select a file from your computer, click the Choose File(s) button [2]. If enabled by your institution, you may be able to select multiple files.
To select a destination folder for your uploaded file, select an option in the Folder drop-down menu [3].
If an uploaded file is a duplicate of an existing file, Canvas displays a prompt asking if the file should be overwritten, renamed, or skipped.
