i am agree with Manas .. i dont think there is any way to filter with drives: but u can to following stuff as shown:

OpenFileDialog ofd = new OpenFileDialog();
ofd.CustomPlaces.Clear();
foreach (var item in System.IO.DriveInfo.GetDrives())
{
if (item.DriveType == DriveType.Removable)
ofd.CustomPlaces.Add(item.RootDirectory.ToString());
}

if (ofd.ShowDialog() == DialogResult.OK)
{
FileInfo f = new FileInfo(ofd.FileName);
string s = f.Directory.Root.ToString();
DriveInfo df = new DriveInfo(s);
if (df.DriveType == DriveType.Removable)
{
//DO STUFF WITH FILE
}
}

Solution 1

I don't think that it is possible to to achieve what you are trying to do with OpenFileDialog.

You can either write your own custom dialog or do validation after you have made the selection.

Solution 3

Use substring function to get the first two characters of the path,
if the path start with \\, it should be a path start with network drive name.
Else, you can cut off the first 3 characters and add the drive name.
