    Problems Moving Certain Folders...

    I am trying to develop this program for a friend, but I've hit a problem: folders on his computer won't move from his C:\ to his Y:\ drive (The Y drive is a folder on his network located on a different computer).

    If I have a normal .txt file and a folder on his desktop, I can move both to another location on his computer without a problem. However, when I try to move them from the desktop to the Y:\ drive, the .txt file (and any file that is not a folder for that matter) WILL move, but the folder will not. I've tried to create other folders in various locations of his harddrive, but still nothing.

    Is this my program? Or is it something perhaps with his network? I'm really not sure what the root of the problem is...? It only affects the folders.

    I'm using the MoveFile() function to move the files... I'm not sure what code to post, it seems to work perfectly until it moves a folder to a different drive.

    Thanks in advance for any help, I really appreciate it.

    Well, if MoveFile fails, it sets the last error, so fetch it with GetLastError and post it.

    What operating system is running on the computer that hosts the Y: drive? Windows Vista has complicated permissions that might allow someone to enable file creation but disable folder creation. Can you create a folder there by hand from explorer?

    Can you create folders with your code on the C: drive?

    Turns out the other drive is actually on the same computer. Sorry about that...
    The computer is running Windows XP Professional.

    Yeah, I can move folders and their contents on the C drive with my code without a problem. Folders don't want to move to the Y:\ drive, though. Individual files will, but folders... nope.

    Elysia, I'm unfamiliar with GetLastError... does it return an integer value? If so, when I move an individual file the value returned is 0, and if I move a folder I recieve a 5. The program doesn't crash or anything, the file just doesn't move.

    Thanks

    The one caveat is that the MoveFile function will fail on directory moves when the destination is on a different volume.
    In other words, MoveFile() is crap.

    Should I use just FileCopy and then FileDelete? What kind of function would allow me to move it to another volume?

    I tried MoveFileEx (http://msdn2.microsoft.com/en-us/library/aa365240.aspx) but that doesn't seem to work, either. Same error: Access Denied. Thanks for letting me know what the 5 represents.

    Code:
    //doesn't work... 
    MoveFileEx(original, destination, MOVEFILE_COPY_ALLOWED);

    I dunno... perhaps try move each file in the folder and create the directories on the other drive.

    The only safe one is SHFileOperation. Tricky, but yes, it works.

    LOL. Nice conclusion.
