How to attach multiple files to a single list item, such as a Task List. Most people know about the “Upload Multiple Documents” option in document libraries. This option isn’t there with list items.

What you can do is attach files individually. You can keep attaching as many files as you like.

  1. Click Attach File from the ribbon
  2. Select first file you want attached
  3. Repeat

The files will now be listed in the “Attachment” section of your list item properties.
