PKEY_ItemNameDisplay

// Name: System.ItemNameDisplay -- PKEY_ItemNameDisplay
// Type: String -- VT_LPWSTR (For variants: VT_BSTR)
// FormatID: (FMTID_Storage) B725F130-47EF-101A-A5F1-02608C9EEBAC, 10 (PID_STG_NAME)
//
// This is the display name in "most complete" form. This is the best effort unique representation
// of the name of an item that makes sense for end users to read. It is the concatentation of
// System.ItemNamePrefix and System.ItemName.
//
// If the item is a file this property
// includes the extension in all cases, and will be localized if a localized name is available.
//
// There are acceptable cases when System.FileName is not VT_EMPTY, yet the value of this property
// is completely different. Email messages are a key example. If the item is an email message,
// the item name is likely the subject. In that case, the value must be the concatenation of the
// System.ItemNamePrefix and System.ItemName. Since the value of System.ItemNamePrefix excludes
// any trailing whitespace, the concatenation must include a whitespace when generating System.ItemNameDisplay.
//
// Note that this property is not guaranteed to be unique, but the idea is to promote the most likely
// candidate that can be unique and also makes sense for end users. For example, for documents, you
// might think about using System.Title as the System.ItemNameDisplay, but in practice the title of
// the documents may not be useful or unique enough to be of value as the sole System.ItemNameDisplay.
// Instead, providing the value of System.FileName as the value of System.ItemNameDisplay is a better
// candidate. In Windows Mail, the emails are stored in the file system as .eml files and the
// System.FileName for those files are not human-friendly as they contain GUIDs. In this example,
// promoting System.Subject as System.ItemNameDisplay makes more sense.
//
// Compatibility notes:
//
// Shell folder implementations on Vista: use PKEY_ItemNameDisplay for the name column when
// you want Explorer to call ISF::GetDisplayNameOf(SHGDN_NORMAL) to get the value of the name. Use
// another PKEY (like PKEY_ItemName) when you want Explorer to call either the folder's property store or
// ISF2::GetDetailsEx in order to get the value of the name.
//
// Shell folder implementations on XP: the first column needs to be the name column, and Explorer
// will call ISF::GetDisplayNameOf to get the value of the name. The PKEY/SCID does not matter.
//
// Example values:
//
// File: "hello.txt"
// Message: "Re: Let's talk about Tom's argyle socks!"
// Device folder: "song.wma"
// Folder: "Documents"

PKEY_ItemTypeText

//  FormatID: (FMTID_Storage) B725F130-47EF-101A-A5F1-02608C9EEBAC, 4 (PID_STG_STORAGETYPE)
//  
//  This is the user friendly type name of the item.  This is not intended to be
//  programmatically parsed.
//  
//  If System.ItemType is VT_EMPTY, the value of this property is also VT_EMPTY.
//  
//  If the item is a file, the value of this property is the same as if you passed the 
//  file's System.ItemType value to PSFormatForDisplay.
//  
//  This property should not be confused with System.Kind, where System.Kind is a high-level
//  user friendly kind name. For example, for a document, System.Kind = "Document" and 
//  System.Item.Type = ".doc" and System.Item.TypeText = "Microsoft Word Document"
//  
//  Example values:
//  
//      If the path is...                     The property value is...
//      -----------------                     ------------------------
//      "c:\foo\bar\hello.txt"                "Text File"
