Create a folder and sub folder in Excel VBA - excel

Question

I have a pull down menu of companies that is populated by a list on another sheet. Three columns, Company, Job #, and Part Number.
When a job is created I need a folder for said company and a sub-folder for said Part Number.
If you go down the path it would look like:
C:\Images\Company Name\Part Number\
If either company name or Part number exists don't create, or overwrite the old one. Just go to next step. So if both folders exist nothing happens, if one or both don't exist create as required.
Another question is there a way to make it so it works on Macs and PCs the same?

Answer 1

Another simple version working on PC:
Sub CreateDir(strPath As String)
Dim elm As Variant
Dim strCheckPath As String
strCheckPath = ""
For Each elm In Split(strPath, "\")
strCheckPath = strCheckPath & elm & "\"
If Len(Dir(strCheckPath, vbDirectory)) = 0 Then MkDir strCheckPath
Next
End Sub

Answer 2

One sub and two functions. The sub builds your path and use the functions to check if the path exists and create if not. If the full path exists already, it will just pass on by.
This will work on PC, but you will have to check what needs to be modified to work on Mac as well.
'requires reference to Microsoft Scripting Runtime
Sub MakeFolder()
Dim strComp As String, strPart As String, strPath As String
strComp = Range("A1") ' assumes company name in A1
strPart = CleanName(Range("C1")) ' assumes part in C1
strPath = "C:\Images\"
If Not FolderExists(strPath & strComp) Then
'company doesn't exist, so create full path
FolderCreate strPath & strComp & "\" & strPart
Else
'company does exist, but does part folder
If Not FolderExists(strPath & strComp & "\" & strPart) Then
FolderCreate strPath & strComp & "\" & strPart
End If
End If
End Sub
Function FolderCreate(ByVal path As String) As Boolean
FolderCreate = True
Dim fso As New FileSystemObject
If Functions.FolderExists(path) Then
Exit Function
Else
On Error GoTo DeadInTheWater
fso.CreateFolder path ' could there be any error with this, like if the path is really screwed up?
Exit Function
End If
DeadInTheWater:
MsgBox "A folder could not be created for the following path: " & path & ". Check the path name and try again."
FolderCreate = False
Exit Function
End Function
Function FolderExists(ByVal path As String) As Boolean
FolderExists = False
Dim fso As New FileSystemObject
If fso.FolderExists(path) Then FolderExists = True
End Function
Function CleanName(strName as String) as String
'will clean part # name so it can be made into valid folder name
'may need to add more lines to get rid of other characters
CleanName = Replace(strName, "/","")
CleanName = Replace(CleanName, "*","")
etc...
End Function

Answer 3

I found a much better way of doing the same, less code, much more efficient. Note that the """" is to quote the path in case it contains blanks in a folder name. Command line mkdir creates any intermediary folder if necessary to make the whole path exist.
If Dir(YourPath, vbDirectory) = "" Then
Shell ("cmd /c mkdir """ & YourPath & """")
End If

Answer 4

Private Sub CommandButton1_Click()
Dim fso As Object
Dim fldrname As String
Dim fldrpath As String
Set fso = CreateObject("scripting.filesystemobject")
fldrname = Format(Now(), "dd-mm-yyyy")
fldrpath = "C:\Temp\" & fldrname
If Not fso.FolderExists(fldrpath) Then
fso.createfolder (fldrpath)
End If
End Sub

Answer 5

There are some good answers on here, so I will just add some process improvements. A better way of determining if the folder exists (does not use FileSystemObjects, which not all computers are allowed to use):
Function FolderExists(FolderPath As String) As Boolean
FolderExists = True
On Error Resume Next
ChDir FolderPath
If Err <> 0 Then FolderExists = False
On Error GoTo 0
End Function
Likewise,
Function FileExists(FileName As String) As Boolean
If Dir(FileName) <> "" Then FileExists = True Else FileExists = False
EndFunction

Answer 6

Function MkDir(ByVal strDir As String)
Dim fso: Set fso = CreateObject("Scripting.FileSystemObject")
If Not fso.FolderExists(strDir) Then
' create parent folder if not exist (recursive)
MkDir (fso.GetParentFolderName(strDir))
' doesn't exist, so create the folder
fso.CreateFolder strDir
End If
End Function

This works like a charm in AutoCad VBA and I grabbed it from an excel forum. I don't know why you all make it so complicated?

Question: I'm not sure if a particular directory exists already. If it doesn't exist, I'd like to create it using VBA code. How can I do this?
Answer: You can test to see if a directory exists using the VBA code below:
(Quotes below are omitted to avoid confusion of programming code)
If Len(Dir("c:\TOTN\Excel\Examples", vbDirectory)) = 0 Then
MkDir "c:\TOTN\Excel\Examples"

For those looking for a cross-platform way that works on both Windows and Mac, the following works:
Sub CreateDir(strPath As String)
Dim elm As Variant
Dim strCheckPath As String
strCheckPath = ""
For Each elm In Split(strPath, Application.PathSeparator)
strCheckPath = strCheckPath & elm & Application.PathSeparator
If (Len(strCheckPath) > 1 And Not FolderExists(strCheckPath)) Then
MkDir strCheckPath
End If
Next
End Sub
Function FolderExists(FolderPath As String) As Boolean
FolderExists = True
On Error Resume Next
ChDir FolderPath
If Err <> 0 Then FolderExists = False
On Error GoTo 0
End Function

Never tried with non Windows systems, but here's the one I have in my library, pretty easy to use. No special library reference required.
Function CreateFolder(ByVal sPath As String) As Boolean
'by Patrick Honorez - www.idevlop.com
'create full sPath at once, if required
'returns False if folder does not exist and could NOT be created, True otherwise
'sample usage: If CreateFolder("C:\toto\test\test") Then debug.print "OK"
'updated 20130422 to handle UNC paths correctly ("\\MyServer\MyShare\MyFolder")
Dim fs As Object
Dim FolderArray
Dim Folder As String, i As Integer, sShare As String
If Right(sPath, 1) = "\" Then sPath = Left(sPath, Len(sPath) - 1)
Set fs = CreateObject("Scripting.FileSystemObject")
'UNC path ? change 3 "\" into 3 "#"
If sPath Like "\\*\*" Then
sPath = Replace(sPath, "\", "#", 1, 3)
End If
'now split
FolderArray = Split(sPath, "\")
'then set back the # into \ in item 0 of array
FolderArray(0) = Replace(FolderArray(0), "#", "\", 1, 3)
On Error GoTo hell
'start from root to end, creating what needs to be
For i = 0 To UBound(FolderArray) Step 1
Folder = Folder & FolderArray(i) & "\"
If Not fs.FolderExists(Folder) Then
fs.CreateFolder (Folder)
End If
Next
CreateFolder = True
hell:
End Function

Here's short sub without error handling that creates subdirectories:
Public Function CreateSubDirs(ByVal vstrPath As String)
Dim marrPath() As String
Dim mint As Integer
marrPath = Split(vstrPath, "\")
vstrPath = marrPath(0) & "\"
For mint = 1 To UBound(marrPath) 'walk down directory tree until not exists
If (Dir(vstrPath, vbDirectory) = "") Then Exit For
vstrPath = vstrPath & marrPath(mint) & "\"
Next mint
MkDir vstrPath
For mint = mint To UBound(marrPath) 'create directories
vstrPath = vstrPath & marrPath(mint) & "\"
MkDir vstrPath
Next mint
End Function

Answer 11

I know this has been answered and there were many good answers already, but for people who come here and look for a solution I could post what I have settled with eventually.
The following code handles both paths to a drive (like "C:\Users...") and to a server address (style: "\Server\Path.."), it takes a path as an argument and automatically strips any file names from it (use "\" at the end if it's already a directory path) and it returns false if for whatever reason the folder could not be created. Oh yes, it also creates sub-sub-sub-directories, if this was requested.
Public Function CreatePathTo(path As String) As Boolean
Dim sect() As String ' path sections
Dim reserve As Integer ' number of path sections that should be left untouched
Dim cPath As String ' temp path
Dim pos As Integer ' position in path
Dim lastDir As Integer ' the last valid path length
Dim i As Integer ' loop var
' unless it all works fine, assume it didn't work:
CreatePathTo = False
' trim any file name and the trailing path separator at the end:
path = Left(path, InStrRev(path, Application.PathSeparator) - 1)
' split the path into directory names
sect = Split(path, "\")
' what kind of path is it?
If (UBound(sect) < 2) Then ' illegal path
Exit Function
ElseIf (InStr(sect(0), ":") = 2) Then
reserve = 0 ' only drive name is reserved
ElseIf (sect(0) = vbNullString) And (sect(1) = vbNullString) Then
reserve = 2 ' server-path - reserve "\\Server\"
Else ' unknown type
Exit Function
End If
' check backwards from where the path is missing:
lastDir = -1
For pos = UBound(sect) To reserve Step -1
' build the path:
cPath = vbNullString
For i = 0 To pos
cPath = cPath & sect(i) & Application.PathSeparator
Next ' i
' check if this path exists:
If (Dir(cPath, vbDirectory) <> vbNullString) Then
lastDir = pos
Exit For
End If
Next ' pos
' create subdirectories from that point onwards:
On Error GoTo Error01
For pos = lastDir + 1 To UBound(sect)
' build the path:
cPath = vbNullString
For i = 0 To pos
cPath = cPath & sect(i) & Application.PathSeparator
Next ' i
' create the directory:
MkDir cPath
Next ' pos
CreatePathTo = True
Exit Function
Error01:
End Function
I hope someone may find this useful. Enjoy! :-)

Answer 12

This is a recursive version that works with letter drives as well as UNC. I used the error catching to implement it but if anyone can do one without, I would be interested to see it. This approach works from the branches to the root so it will be somewhat usable when you don't have permissions in the root and lower parts of the directory tree.
' Reverse create directory path. This will create the directory tree from the top down to the root.
' Useful when working on network drives where you may not have access to the directories close to the root
Sub RevCreateDir(strCheckPath As String)
On Error GoTo goUpOneDir:
If Len(Dir(strCheckPath, vbDirectory)) = 0 And Len(strCheckPath) > 2 Then
MkDir strCheckPath
End If
Exit Sub
' Only go up the tree if error code Path not found (76).
goUpOneDir:
If Err.Number = 76 Then
Call RevCreateDir(Left(strCheckPath, InStrRev(strCheckPath, "\") - 1))
Call RevCreateDir(strCheckPath)
End If
End Sub
