Question: I'm pulling a file path from a database to use as a file source.
I need to remove the last folder from the source path, so I can then create new folders to use as the destination path.

Example source file path:
`\\\\ServerName\\Documents\\MasterDocumentFolder\\`

I need to remove the last folder from that string and get this:
`\\\\ServerName\\Documents\\`

So I can create a folder like this:
`\\\\ServerName\\Documents\\NewDocumentFolder1\\`

Edit: I have updated my example paths to show why the Path.GetDirectoryName() won't work in this case.

Answer: 
With this method you can create dir by dirPath (if dir is not exist) and to create directory from the filePath if needed

```
private void CreateDirIfNotExist(string dirPath, bool removeFilename = false)
{
    if (removeFilename)
        dirPath = Directory.GetParent(dirPath).FullName;

    if (!Directory.Exists(dirPath))
        Directory.CreateDirectory(dirPath);
}

```
In VB:

```
Dim MyNewPath As String = StrReverse(Strings.Split(StrReverse(MyPath), "\", 2)(1))

```

This works down to the root, eg `C:\MyPath` but fails (without validation) for a bare folder.

Obviously, you need to handle differently if there is a file appended.
