How to Open a .Xsd File in Adobe Acrobat Readerby Stephen Lilley
An XSD computer file is a text-based file that contains instructions for the XML file it is associated with. Typically an XSD file contains data relating to exactly how the associated XML file will display its information. If you want to open an XSD file in the copy of Adobe Acrobat Reader that is installed on your computer, you can, but keep in mind that you will only be able to view the file's contents. You also won't be able to make any changes or additions to it.
Open "Adobe Reader." An icon for Adobe Reader is in your "Start" menu.
Click Adobe Reader's "File" menu.
Use the "Open" dialog box to select the icon for your XSD file. Once selected, click the "Open" button again to open your XSD file in Adobe Reader.
