MkDir Command - how to use with the filename

[mel_flynn]

I need to use the MkDir Command when the string contains the required directory to be made and the filename.
e.g. I want to create a directory 'Directory1'

Dim fileLocation as String
fileLocation = "C:\Root\Directory1\file1.txt"

MkDir fileLocation

But I keep getting a Run-time error '76' Path not found. I know this is because I have the filename included in the string. How can I include the filename in the string without running into error?

Note: The file doesn't have to be created just the directory
