Remarks

PKEY values are defined in Propkey.h.

The value for System.ItemType is intended to be programmatically parsed, and can be either:

  • A file extension that points to a ProgID value (HKEY_CLASSES_ROOT\<ProgID>) holding the display name for the type.
  • A ProgID value (HKEY_CLASSES_RROOT\<ProgID>), containing the display name for the type.

The FriendlyTypeName element of a ProgID should be a localized version of the application name (@winword.dll,-42), while the default value of the ProgID key is a non-localized name (Word.Document.12).

If there is no canonical type, the value is VT_EMPTY. If the item is a file (System.FileName is not VT_EMPTY), the value is the same as System.FileExtension. Use System.ItemTypeText when you want to display the type to end users in a view.

Note

If the item is a file, passing the System.ItemType value to PSFormatForDisplay results in the same value as System.ItemTypeText.

 

Example values:

Path ItemType
c:\mydir\bar\hello.txt .txt
\\server\share\mydir\goodnews.doc .doc
\\server\share\folder Directory
c:\MyDir\MyFolder Directory
[desktop] Folder
/Mailbox Account/Inbox/'Re: Hello!' MAPI/IPM.Message
