The attachments field allows users to upload files, URLs (web links), or both to an object. Most standard file types are accepted by this field; however, there are some restrictions (see below). If a supported document file is uploaded to this field, it's possible to search for those documents by keywords in the file name and/or contents or by upload date. See the Attachment Searches article for more details.

When the File only or File and web link option is selected in the field's settings, users can upload files (up to 100 MB in size) or web links by clicking the file or web link upload area on a form (as shown in the screenshot above).
