If you have a lot of files to add to your course, you can bulk upload them.
You can also bulk upload files by dragging and dropping the files into Canvas from your computer. However, sometimes too many files can cause problems. If you have more than 50 files, try zipping the files and uploading the ZIP file into your course.
If you are using Usage Rights, you must set the file usage rights before the files can be published.
Canvas does not support file uploads larger than 5 GB.
In Course Navigation, click the Files link.
Click the Upload button.

To select a group of files, hold down the Shift key on your keyboard and click the first and last files in the group.
To select multiple files, hold down the Control (Windows) or Command (Mac) key on your keyboard and click each file.
