The limitations have been pulled from Windows SDK header file

Sparse files are only supported under Windows 2000 and later and the file must be on a volume that is NTFS 5.0 or later.

MSDN: Windows Clipboard API

* Load required Windows API functions
=LoadApiDlls()
 
* Open clipboard
lnResult = OpenClipboard(_SCREEN.hWnd)
* Get handle on file list structure ( Format type 15)
lnHdrop = GetClipboardData (15)
IF lnHdrop > 0
	lcBuffer = SPACE(512)
	lnSize = LEN(lcBuffer)
        * Get number of files in the list
	lnFile = BITOR(0xFFFFFFFF,0)
	lnFileCount = DragQueryFile(lnHdrop, lnFile, @lcBuffer, lnSize  )
 
        * Get each file name

Code below shows how to retrieve file date and time using native VFP commands or WSH. For Windows API based solution that also allows to set file date and time, see George Tasker's Windows Time hosted on UT

MSDN links:

• WSH FileSystemObject Object
• WSH File Object

The CopyFile() and MoveFile() WIN API functions preserve the case of the name for the destination file. Alternatively, WSH can be used.
The source and destination file names should include the directory name in both cases.

Note 1 A Copy operation will not change file name case when destination file already exists (overwritten).

Note 2 The WinApiErrMsg is used to retrieve Windows API error message in case of error.
