Copy Directory

Hi,

I use copyfile() to copy a single file.
Is there a function to copy a complete directory?

Thanks

Dear Marc,

AEval( Directory( "*.prg" ), { | aFile | CopyFile( aFile[ 1 ], "path\" + aFile[ 1 ] ) } )

Using Windows FileSystem Object, we can copy entire folder with one line of code:

Code: Select all | Expand

oFs:CopyFolder( cSourceFolder\*.*, cDestFolder, lOverWrite )
We need to make sure the destination folder exists and if not create it first.

This is a working example:

Code: Select all | Expand

function TestCopyFolder()

   local cSrcFolder  := "c:\fwh\bitmaps\"
   local cDstFolder  := "c:\myimages\fwh\"
   local oFs, lCopied := .f.

   oFs   := FileSysObj()
   if oFs:FolderExists( cDstFolder ) .or. ;
      lMkFullPath( cDstFolder )
      //
      TRY
         oFs:CopyFolder( cSrcFolder + "*.*", cDstFolder, .t. )
         lCopied  := .t.
      CATCH
      END
   endif

   ? lCopied


return nil
Note: If you do not have FWH function FileSys() in your version of FWH, we can create filesystem object this way:

Code: Select all | Expand

oFS   := CreateObject( "Scripting.FileSystemObject" )

Friends:

My five cents, Take a look at the RoboCopy() windows command

Regards

Windows command RoboCopy is more powerful than XCopy.
We consider using WinExec( "robocopy .... " )

But to copy a file, we do not use WinExec( "copy file1 file2" ), though this is also can be used.
Same way instead of WinExec( "xcopy .. " ), we better use any functions provided by Windows, like oFs:CopyFolder

hi,

the Windows Explorer Way to "copy" files are ShFileOperation() API

Code: Select all | Expand

HB_FUNC( SHFILE )
{
   #ifndef _WIN64
      HWND hWnd = ( HWND ) hb_parnl( 1 );
   #else
      HWND hWnd = ( HWND ) hb_parnll( 1 );
   #endif

   SHFILEOPSTRUCT sh;

   memset( ( char * ) &sh, 0, sizeof( sh ) );

   sh.hwnd   = hWnd ;
   sh.wFunc  = ( UINT ) hb_parnl( 2 );
   sh.pFrom  = ( LPSTR ) hb_parc( 3 );
   sh.pTo    = ( LPSTR ) hb_parc( 4 );
   sh.fFlags = ( FILEOP_FLAGS ) hb_parnl( 5 );
   sh.hNameMappings = 0;
   sh.lpszProgressTitle = NULL;

   hb_retnl( SHFileOperation( &sh ) );
}
call it using this

Nice.
Can you please show an example usage of the function ShellFiles(...) to copy a folder like this?
c:\fwh\bitmaps\*.* (including sub-folders)
to
c:\myimages\fwh\ (create folders if they do not exist)

Folder default are copy recursive so it is simple

Code: Select all | Expand

   Start_SHfunc( {"bitmaps",0,DATE(),TIME(),"D"}, "COPY", "c:\fwh\", "c:\myimages\fwh\", .F., .F. )
1.st Parameter is a Array with Elements from DIRECTORY()
here in Sample it is only Folder "bitmaps" in Array

Code: Select all | Expand

FUNCTION Start_SHfunc( aItem, cAction, cSourceDir, cTargetDir, lConfirm, lPaperbin )
LOCAL ii, iMax
LOCAL cFile, cAttr
LOCAL acFiles  := {}
LOCAL acTarget := {}
LOCAL lRet := .F.

   iMax := LEN( aItem )
   FOR ii := 1 TO iMax

      cFile := aItem[ ii ] [ F_NAME ]
      cAttr := aItem[ ii ] [ F_ATTR ]

      AADD( acFiles, cSourceDir + cFile )

      IF cAction = "DELETE"
         AADD( acTarget, "" + CHR( 0 ) )
      ELSE
         AADD( acTarget, cTargetDir + cFile )
      ENDIF

   NEXT

   lRet := DoSH3func( cAction, lConfirm, lPaperbin, acFiles, acTarget )

RETURN lRet
as you see it build Array with "full-path" which depend on cSourceDir + cFile / cTargetDir + cFile
i use Result from "Everything" instead of DIRECTORY() so it can also be different SourceDir

p.s. as ShFileOperation can show Animation "open" full Detail

Thanks
I don't know "Everything", but I understand we need to get the names into an array by recursion.
Thanks again.

Btw, Harbour has a function DirectoryRecurse().

Jimmy,

Is this now running for standard FWH or for your Software Tools ?

HB_FUNC( SHFILE ) is general for harbour 32 / 64 Bit
Demo c:\fwh\samples\dlgfile.prg only are for 32 Bit

other *.PRG may different like

Code: Select all | Expand

  DEFAULT acFiles TO
 DEFAULT acFiles :=
---

i have "split" *.PRG as i call it in different Situation e.g. "dragdrop"

Code: Select all | Expand

LOCAL aItem := ::oGrid:Getdata()
this will get all "marked" Files in TGrid()
