I am using Directoryinfo object to move a directory on c:\ to d:\. But it's not possiable as destination cannot be another disk volume.
Is there a way that I can move or copy a folder to another volume.

Thanks Christian
This only moves the files.
What i want is to move the whole directory to another volume.
I have a directory with thousands of files. I want to move the entire directory to another volume.

Even this dosen't work across volumes. I have already tried this.

It won't copy from the C drive the to D drive ? I find that hard to believe.

I know but it dosen't work.
There is no mention about this in the documentation but when you try it, it gives you the error that
Move will not work across volumes

Damn - you're right.

This C# code:

Directory.CreateDirectory(@"\\warlock\c$\1.0");
string [] files = Directory.GetFiles(@"c:\1.0");
foreach(string file in files)
{
File.Copy(file, Path.Combine( @"\\warlock\C$\1.0", Path.GetFileName(file)));
}

Directory.Delete(@"c:\1.0");

worked fine to move a directory to another computer, so I'm sure it will do what you want.

Thanks Christian,
This is again moving files across the volumes.
I guess microsoft dosen't provide function for moving directories across volumes.

Tha'ts because it's physically impossible to "move" files to different volumes.

You move "move" directories/files inside the same volume because all that is required is manipulating directory entry pointers so that the files appear under the new directory. No file data is ever "moved" or "copied" to make this happen. This, obviously, can't be done acrossed volumes.

So, in order to "move" files/directories to another volume, the source files/directories must be copied to the destination, then removed from the source.

Thanks Dave, another reason can be that moving directories across volumes can result in freeing up permissions on the directory and there can be a possiability that user might be moving the directory from a fat to ntfs and vice versa

Can i read the length of the directory.
What i want is to increment the progressbar during thr directory.move.
If i can read the bytes that are moved , then accordingly i can increment the progress bar.
Directory is about 150mb

or

Is there a way of incrementing the progressbar during the move process.

It all depends on what your using to do the move. If you use Directory.Move to move an entire batch of files all at once, you don't get any information back on status, and therefore, nothing usable to update a ProgressBar.

If you want to use a progressbar, you'll have to write the code to "move" the files yourself, one at a time. You'll also have to supply the methods for reporting status and progress.

Yes, it is. And it works. What's the problem ? To 'move' the files, the code I provided created a directory on another machine, copied the files over and deleted them. It *works*, I tested it.

It's no problem if the directory contains no other directory, but if it contains multiple directories then it would be a problem.

Is .NET that much better than VB6?

I currently use VB6 and have been toying with the idea of switching to .NET

I have heard the .NET was all together a better program than VB6 from some but from others I heard that it was complete rubbish and are happy they went back to VB6.

Just trying to get some opinions of fellow VB6/.NET users

-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-
Code is a beautiful thing

Theres nothing like the feeling you get when you create your first program.No matter how basic
