Adobe Reader 6.0 and Adobe Reader 7.x allow you save a copy of a PDF file to your local hard disk. However, they do not let you save changes you make (such as incremental saves while filling out a form) unless the PDF file is rights-enabled. To save changes in a PDF file that is not rights-enabled, you must use Adobe Acrobat Standard or Professional. For information about purchasing Acrobat 6.0 Standard or Professional, visit the Adobe website at http://store.adobe.com/store/products/department.jhtml?id=deptAcrobatFamily .

You can use Adobe LiveCycle Reader Extensions to create a rights-enabled PDF form that enables Adobe Reader users to comment on, complete, save, distribute, submit, and add digital signatures to the form. When you open a rights-enabled PDF form in Adobe Reader, a dialog box appears outlining the extended capabilities of the PDF file.

To view or download sample rights-enabled PDF forms and to learn more about Adobe LiveCycle Reader Extensions, visit the Adobe website at www.adobe.com/products/server/readerextensions/ .
