c# - Directory.Delete doesn't work. Access denied error but under Windows Explorer it's ok

Question

I have searched the SO but find nothing.

Why this doesn't work?

Directory.Delete(@"E:3{90120000-001A-0000-0000-0000000FF1CE}-C");

Above line will throw exception "Access is denied". I have admin rigths and I can delete the dir with Explorer.

It looks like some forbidden chars? but Windows Explorer can handle it. How can I delete directories with names like that?

Answer 1

Thank you all for your input, it helps me in quick find of solution.

As Phil mentioned "Directory.Delete fails if it is, regardless of permissions (see bottom of msdn.microsoft.com/en-us/library/…)"

In addition Unable to remove Read-Only attribute from folder Microsoft says:

You may be unable to remove the Read-Only attribute from a folder using Windows Explorer. In addition, some programs may display error messages when you try to save files to the folder.

Conclusion: always remove all dir,file attributes diffrent then Normal before deleting. So below code solve the problem:

System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo(@"E:3{90120000-0021-0000-0000-0000000FF1CE}-C1");

if (dir.Exists)
{
    setAttributesNormal(dir);
    dir.Delete(true);
}

. . .

function setAttributesNormal(DirectoryInfo dir) {
    foreach (var subDir in dir.GetDirectories())
        setAttributesNormal(subDir);
    foreach (var file in dir.GetFiles())
    {
        file.Attributes = FileAttributes.Normal;
    }
}
