Here is an alternate approach. Create a C DLL with this exported function:

extern "C" __declspec(dllexport) void MoveDirectory(
    const wchar_t* source, const wchar_t* destination)
    SHFILEOPSTRUCT fop = {};
    fop.wFunc = FO_MOVE;
    fop.pFrom = source;
    fop.pTo = destination;
    SHFileOperation (&fop);

And P/Invoke it from C#:

[DllImport("SomeLib.dll", CharSet = CharSet.Unicode,
    CallingConvention = CallingConvention.Cdecl)]
public static extern void MoveDirectory(string source, string destination);
static void Main()
    MoveDirectory("c:\\abc\0", "d:\\abc\0");

Notice the extra NULLs I added to the string. That is required and is not a typo.

First, thanx for your help

but when i chose a folder i did not know where the folder is(in C or in D), aaaaaaaaaaaaaaah

Not sure I understand this. If you let the user pick a folder, surely you know the full path for it (including the drive).

Are you using Directory.Move? If so, what error do you get when you try to move to a different drive?

More info:[^][^]


Yes, that won't work across volumes. You could recursively create directories and copy files over, and then delete the source directory. It's a bit of work but a quick google search reveals a few existing solutions (people have written recursive methods to do this).

Yes, i used Directory.Move

the message " the source and the destination must be in the similar root".
Member 7886123 10-May-11 11:05am
this is the exact message " Source and destination path must have identical roots. Move will not work across volumes".

Yeah, check my updated answer.
Member 7886123 10-May-11 11:20am

There's an alternate way which I'll post as an alternate solution.
Member 7886123 10-May-11 11:25am
you know what, i have to change the file's name while moving the folder !!!!
Nishant Sivakumar 10-May-11 11:34am
Well, that makes it crazier huh? Although you could do it after the move. See my alternate way.
