# How to recursively add missing directories

How do I recursively add any required (missing) subdirectories using FSO?

For example, I want to have a function that will accept a folder name such as C:\folder1\folder2\folder3

What I need is to create any missing folders from that full path.
So if I already have C:\folder1 and it already has folder2, I want folder3 to be created.  When I pass the full path name, I dont know what folders, if any, already exist.

If I don’t have ANY of the folders, I want the entire path to be created.

I could pass \\server\directory\folder1\folder2\folder3 or U:\Reports\Sales\2007\
I can verify that the server/drive exists… but not how to recursively build the list of folders.

I can verify that there is no filename in that list… all I need is a function (or functions) that will make sure that the entire directory specified exists.  So by the time the function is done, I don’t have to check does folder exist or anything like that.

Thanks!

This should do it:
path = "C:\test\folder\to\create"

Set fso = CreateObject("Scripting.FileSystemObject")
parts = Split(path, "\")
temp = parts(0) & "\"

For i = 1 To UBound(parts)
temp = temp & parts(i) & "\"

If Not fso.FolderExists(temp) Then
fso.CreateFolder(temp)
End If
Next

Simply call System.IO.Directory.CreateDirectory(directoryName) with the full path, it creates the directories for you!

>>  Simply call System.IO.Directory.CreateDirectory(directoryName) with the full path,

In classic VB? I believe you're thinking of .NET  :)
