You mean this article ?: http://blogs.technet.com/b/markrussinovich/archive/2008/02/04/2826167.aspx
Mark Russinovitch says in that very article: "The changes apply both to Explorer copies as well as to ones initiated by applications using the CopyFileEx API" So just call CopyFileEx()... no need to try to hook into Windows Explorer. (Is there a "let me read that article for you" equivalent to "Let me google that for you" ?) ;) -----Original Message----- From: delphi-boun...@delphi.org.nz [mailto:delphi-boun...@delphi.org.nz] On Behalf Of John Bird Sent: Friday, 13 May 2011 13:35 To: NZ Borland Developers Group - Delphi List Subject: Re: [DUG] API to Windows explorer Now back to the original question - is there an API to Windows Explorer to copy files? ( I have a nice component HAHFindFile to build the list of folders and files in a stringlist, and a routine using TFilestream to do the copy, but I was thinking its almost certainly going to be faster and more robust if there were an API to Windows Explorer to pass the source and destination folders to, and some parameters (eg copy only newer). I read technical articles from Mark Russinovitch about how Vista and Windows 7 optimise copying files over a network, varying the block sizes etc and using caching so I would expect an OS-level API to be much faster. Does anyone know if such an API exists, and are there options to eg copy only later files. I saw some hints in Google about a COM interface to Windows Explorer, but no details if it has options like I am interested in.)
