How to : Give me the details or file summary info

Give me the details or file summary info How to read File Summary Information for non Office files On Windows 2000 you can right-click in Explorer to get the file properties on any file and can associate summary information to any type of files including even text files. For Word or Excel documents compound files the summary information is a part of document itself. For other types of files the way of storing additional information are different.
This feature are only available on volumes formatted with NTFS.
The NTFS implementation stores property sets in alternate streams of an NTFS file.
The alternate streams must be copied when the main file is copied.
However not all file systems support such streams.
For example if an NTFS file with property sets is copied to a FAT volume only the data in the file is copied the property set is lost. First thing you probably want do is to detect whether the current volume is NTFS: IsNTFS - Verifies whether the files volume is NTFS function IsNTFSAFileName : string : boolean var fso drv : OleVariant begin IsNTFS : False fso : CreateOleObject Scripting.FileSystemObject drv : fso.GetDrivefso.GetDriveNameAFileName if drv.FileSystem NTFS then IsNTFS : True end But how to read these properties? Is it really nessesary to work with a streams? No NTFS file system 5.0 provides an implementation of IPropertySetStorage interface for files on an NTFS volume when the files themselves are not compound files.
To get a pointer to the NTFS implementation of IPropertySetStorage we have to call the StgCreateStorageEx function: function StgOpenStorageEx const pwcsName : POleStr Pointer to the path of the file containing storage object grfMode : LongInt Specifies the access mode for the object stgfmt : DWORD Specifies the storage file format grfAttrs : DWORD Reserved must be zero pStgOptions : Pointer Address of STGOPTIONS pointer reserved2 : Pointer Reserved must be zero riid : PGUID Specifies the GUID of the interface pointer out stgOpen : Address of an interface pointer IStorage : HResult stdcall external ole32.dll All Microsoft Windows 2000 applications should use this new function StgOpenStorageEx instead of StgOpenStorage to take advantage of the enhanced Windows 2000 Structured Storage features. The implementation of IPropertySetStorage on NTFS file system is similar with compound file implementation and available only on Windows 2000.
Windows 95 and Windows NT 4.0 and earlier versions cannot access this interface. However you cannot obtain the NTFS implementation of IPropertySetStorage for a compound file.
When opening a compound file with StgOpenStorage specifying the STGFMT_FILE enumeration value results in an error. The next function dumps all properties of the specific file.
By changing the STGFMT_FILE flag in the StgOpenStorageEx call to STGMT_ANY you can open a Structured Storage property set or an NTFS file system property set. function GetFileSummaryInfo const FileName: WideString: String const FmtID_SummaryInformation: TGUID F29F85E0-4FF9-1068-AB91-08002B27B3D9 FMTID_DocSummaryInformation : TGUID D5CDD502-2E9C-101B-9397-08002B2CF9AE FMTID_UserDefinedProperties : TGUID D5CDD505-2E9C-101B-9397-08002B2CF9AE IID_IPropertySetStorage : TGUID 0000013A-0000-0000-C000-000000000046 const STGFMT_FILE 3 Indicates that the file must not be a compound file. This element is only valid when using the StgCreateStorageEx or StgOpenStorageEx functions to access the NTFS file system implementation of the IPropertySetStorage interface. Therefore these functions return an error if the riid parameter does not specify the IPropertySetStorage interface or if the specified file is not located on an NTFS file system volume. STGFMT_ANY 4 Indicates that the system will determine the file type and use the appropriate structured storage or property set implementation. This value cannot be used with the StgCreateStorageEx function.
