How to Delete Schemas
Sometimes you might want to not only exclude a schema from its BizTalk project, but also completely remove the schema from your hard disk. This is known as deleting, as opposed to excluding, a schema. This topic describes the steps required to delete a schema.
To delete a schema
In Solution Explorer, right-click the schema that you want to delete, and then click Delete.
In the confirmation dialog box, click OK.
Note
Deleted schemas are permanently removed from the file system, so proceed cautiously and back up your files regularly.
