Create subfolders within folders...

This might be fairly simple..

I need to check and then create subfolders within a folder.
For instance, the path specified to my application is: C:\MyFolder\MyProjects\MyTestApp
\MyTestFile

At each level, I need to check if the folder exists, if it does then proceed checking the next level, else create it. i.e
Check if MyFolder exists.
If yes then check if MyProjects Exists
If no then create MyFolder folder
and so on.

I DO NOT wish to use the FileSystemObject mechanism to accomplish this.

I would really appreciate any help on this.

Thanks.

vinnyd79,
Thank you for your response. The code works fine.

I have a question though:-
My application will be receiving several files that will written into the same folder. So once the folder is created, I do not think there is a need to CreateNewDirectory everytime a file is written to Path just created. Is there a way a check can be done if the Path exists before creating one?

Thanks!

My concern is the folders can be purged anytime during the day, which might need my code to create the directory. But majority of the times only checking if the directory exists should suffice.

vinnyd79

use dir to check if it exists

Private Sub Command1_Click()
If Dir("C:\Folder\Projects\MyTest", vbDirectory) <> "" Then
MsgBox "it exists"
Else
MsgBox "it don't exist"
' Then create directory here
End If
End Sub

Just as an alternative, here is a routine that I use to make a nested directory set. It uses

Public Const FILE_ATTRIBUTE_DIRECTORY As Long = &H10&
Public Const FILE_ATTRIBUTE_INVALID As Long = -1& ' = &HFFFFFFFF&
Private Declare Function GetFileAttributes Lib "kernel32" Alias "GetFileAttributesA" (ByVal lpfilename As String) As Long

Public Function DirExists(sPathName) As Boolean
Dim attr As Long

attr = GetFileAttributes(sPathName)

If (attr = FILE_ATTRIBUTE_INVALID) Then
DirExists = False
Else
DirExists = ((attr And FILE_ATTRIBUTE_DIRECTORY) > 0)
End If
End Function

Public Sub MkDirLong(ByVal sPath As String, Optional IsNetworkPath As Boolean = False)
Dim sBuild As String
Dim I As Integer

I = InStr(sPath, ":")
If I > 0 Then
sBuild = Left(sPath, 2)
sPath = Mid(sPath, 3)
Else
If Not IsNetworkPath Then
sBuild = "C:" ' Default to C drive
Else
sBuild = "" ' Assume Current Drive if NetworkPath and No Drive Specified
End If
End If

If Right(sPath, 1) <> "\" Then sPath = sPath & "\"

I = InStr(2, sPath, "\")

Do While I > 0
sBuild = sBuild & Left(sPath, I - 1)
sPath = Mid(sPath, I)
If Not DirExists(sDrive & sBuild) Then
MkDir sBuild
End If
I = InStr(2, sPath, "\")
Loop
End Sub

To use this:
Private Sub MakeStorage()

Dim sFilePath As String

sFilePath = "C:\MyProgram\MyData\20020716\AM\" ' Sample path
If Not DirExists(sFilePath) Then MkDirLong(sFilePath)

End Sub
