MoveFile Function

[Ati2ude]

Has anyone ever used the MoveFile function to move an entire directory? I can use the function to move a single file at a time, but MSDN states that the function will move an entire directory including children.

Any help would be great!!

Thanks in advance.

On MSDN You can find:
1. The one caveat is that the MoveFile function will fail on directory moves when the destination is on a different volume.
2. The MAPI version of the MoveFile function won't move a directory. This function always works across drives, and it always performs a copy operation then deletes the original file, as opposed to truly performing a move operation.

It is better to use CopyFile() for moving files in directories (You must then use FinFirstFile(), CreateDirectory() etc., but it works allways).

tchouch,

You are absolutely correct. My feeling is that MSDN is mis-leading here. So I wrote a function that will move a entire directory recursively.

The only caveat here is that you do not want to move the folder to the same path.

I have posted the code for anyone else they may have the same problem.

HANDLE dir;
WIN32_FIND_DATA fd;
HINSTANCE inst;
char sOldFileName[255];
char sNewFileName[255];
char sOldDirName[255];
char sNewDirName[255];


if (!FileExists(sOldPath))
return FALSE;


if (CreateFolderBuildTree(sNewPath.GetBuffer (sNewPath.GetLength())) == -1)
return FALSE;

strcpy(sOldDirName, sOldPath);
strcat(sOldDirName, "\\*.*"

if (sNewPath.Right(1) != "\\&quot
sNewPath += "\\";
if (sOldPath.Right(1) != "\\&quot
sOldPath += "\\";

dir = FindFirstFile(sOldDirName, &fd );
if(dir != NULL && dir != INVALID_HANDLE_VALUE)
{
while (1)
{
if(dir != NULL)
{
if (fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
{
if (strcmp(fd.cFileName, ".&quot == 0 || strcmp(fd.cFileName, "..&quot == 0)
{
}
else
{
//recursively call our function to get sub dirs
if (MoveDirectory(sOldPath + fd.cFileName, sNewPath + fd.cFileName))
DeleteFolder(sOldPath + fd.cFileName);
}
}
else
{
//Build the full path to the old file
strcpy(sOldFileName, sOldPath);
strcat(sOldFileName, fd.cFileName);

//Build the full path to the new file
strcpy(sNewFileName, sNewPath);
strcat(sNewFileName, fd.cFileName);

//Move to new folder
int iRet = rename(sOldFileName, sNewFileName);

}

//Check the next file - if not found then exit
if(!FindNextFile(dir, &fd))
{
break;
}
}
else
break;
}
}
FindClose(dir);


return TRUE;
