Sample
//C#
private void DeleteAllAttachments(PDFXEdit.IPXV_Document Doc, PDFXEdit.IPXV_Inst Inst)
{

PDFXEdit.ICabNode options = Op.Params.Root["Options"];
PDFXEdit.IPXC_NameTree Tree = Doc.CoreDoc.GetNameTree("EmbeddedFiles");
PDFXEdit.IAFS_Inst fsInst = (PDFXEdit.IAFS_Inst)Inst.GetExtension("AFS");
