How to: Create a Directory in Visual Basic

Use the CreateDirectory method of the My.Computer.FileSystem object to create directories.

If the directory already exists, no exception is thrown.

To create a directory

• Use the CreateDirectory method by specifying the full path of the location where the directory should be created. This example creates the directory NewDirectory in C:\Documents and Settings\All Users\Documents.

  My.Computer.FileSystem.CreateDirectory(
    "C:\Documents and Settings\All Users\Documents\NewDirectory")
