Скачать или смотреть selecting, moving and deleting multiple files in Canvas

To delete files from your Canvas course, click "Files" in the course menu
To select more than one file, use Ctrl (or Command) A to select all, or hold the Ctrl (Commend) key as you click to select multiple files. Key tip: Don't click the file name, as this will open that file in a preview window, click further along the file's list row to avoid opening the preview.
To delete multiple files, select the files and then either click the trash can icon, or drop down the cog wheel on one of the selected files.
To move multiple files, create a folder for where you want to move the files and it will appear in the left column of the files. Select the files you want to move then drag and drop them into the left folder.
