File and Folder Procedures
Posted: 4 Sep 03 (Edited 8 May 04)

The following procedures demonstrate creating, copying, moving and deleting of files and folders using VBA:

I know it's long, but it's worth it!

Let's start with the File Procedures


Check if a file exists

CODE

Sub FileExists()
Dim fso
Dim file As String
file = "C:\Test.xls" ' change to match the file w/Path
Set fso = CreateObject("Scripting.FileSystemObject")
If Not fso.FileExists(file) Then
    MsgBox file & " was not located.", vbInformation, "File Not Found"
Else
    MsgBox file & " has been located.", vbInformation, "File Found"
End If
End Sub

Copy a file if it exists

CODE

Sub CopyFile()
Dim fso
Dim file As String, sfol As String, dfol As String
file = "test.xls" ' change to match the file name
sfol = "C:\" ' change to match the source folder path
dfol = "E:\" ' change to match the destination folder path
Set fso = CreateObject("Scripting.FileSystemObject")
If Not fso.FileExists(sfol & file) Then
    MsgBox sfol & file & " does not exist!", vbExclamation, "Source File Missing"
ElseIf Not fso.FileExists(dfol & file) Then
    fso.CopyFile (sfol & file), dfol, True
Else
    MsgBox dfol & file & " already exists!", vbExclamation, "Destination File Exists"
End If
End Sub

Move a file if it exists

CODE

Sub MoveFile()
Dim fso
Dim file As String, sfol As String, dfol As String
file = "test.xls" ' change to match the file name
sfol = "C:\" ' change to match the source folder path
dfol = "E:\" ' change to match the destination folder path
Set fso = CreateObject("Scripting.FileSystemObject")
If Not fso.FileExists(sfol & file) Then
    MsgBox sfol & file & " does not exist!", vbExclamation, "Source File Missing"
ElseIf Not fso.FileExists(dfol & file) Then
    fso.MoveFile (sfol & file), dfol
Else
    MsgBox dfol & file & " already exists!", vbExclamation, "Destination File Exists"
End If
End Sub

Delete a file if it exists

CODE

Sub DeleteFile()
Dim fso
Dim file As String
file = "C:\test.xls" ' change to match the file w/Path
Set fso = CreateObject("Scripting.FileSystemObject")
If fso.FileExists(file) Then
    fso.DeleteFile file, True
Else
    MsgBox file & " does not exist or has already been deleted!" _
            , vbExclamation, "File not Found"
End If
End Sub


Here are the Folder Procedures


Check if a folder exists

CODE

Sub FolderExists()
Dim fso
Dim folder As String
folder = "C:\My Documents" ' change to match the folder path
Set fso = CreateObject("Scripting.FileSystemObject")
If fso.FolderExists(folder) Then
    MsgBox folder & " is a valid folder/path.", vbInformation, "Path Exists"
Else
    MsgBox folder & " is not a valid folder/path.", vbInformation, "Invalid Path"
End If
End Sub

Create a folder if it doesn't exist

CODE

Sub CreateFolder()
Dim fso
Dim fol As String
fol = "c:\MyFolder" ' change to match the folder path
Set fso = CreateObject("Scripting.FileSystemObject")
If Not fso.FolderExists(fol) Then
    fso.CreateFolder (fol)
Else
    MsgBox fol & " already exists!", vbExclamation, "Folder Exists"
End If
End Sub

Copy a folder if it exists

CODE

Sub CopyFolder()
Dim fso
Dim sfol As String, dfol As String
sfol = "c:\MyFolder" ' change to match the source folder path
dfol = "e:\MyFolder" ' change to match the destination folder path
Set fso = CreateObject("Scripting.FileSystemObject")
If Not fso.FolderExists(dfol) Then
    fso.CopyFolder sfol, dfol
Else
    MsgBox dfol & " already exists!", vbExclamation, "Folder Exists"
End If
End Sub

Move a folder if it exists

CODE

Sub MoveFolder()
' ***********************************************************
' ***      This will only work if your operating system   ***
' ***          allows it otherwise an error occurs        ***
' ***********************************************************

Dim fso
Dim fol As String, dest As String
sfol = "c:\MyFolder" ' change to match the source folder path
dfol = "e:\MyFolder" ' change to match the destination folder path
Set fso = CreateObject("Scripting.FileSystemObject")
If Not fso.FolderExists(dfol) Then
    fso.MoveFolder sfol, dfol
Else
    MsgBox dfol & " already exists!", vbExclamation, "Folder Exists"
End If
End Sub

Delete a folder if it exists

CODE

Sub DeleteFolder()
' ***********************************************************
' *** This will delete a folder even if it contains files ***
' ***                 Use With Caution                    ***
' ***********************************************************

Dim fso
Dim fol As String
fol = "c:\MyFolder" ' change to match the folder path
Set fso = CreateObject("Scripting.FileSystemObject")
If fso.FolderExists(fol) Then
    fso.DeleteFolder fol
Else
    MsgBox fol & " does not exist or has already been deleted!" _
        , vbExclamation, "Folder not Found"
End If
End Sub

A couple more procedures that might come in handy!

Move ALL files (or of a specific file type) from one folder into another folder

CODE

Sub MoveFilesFolder2Folder()
Dim fso
Dim sfol As String, dfol As String
sfol = "c:\MyFolder" ' change to match the source folder path
dfol = "e:\MyFolder" ' change to match the destination folder path
Set fso = CreateObject("Scripting.FileSystemObject")
On Error Resume Next
If Not fso.FolderExists(sfol) Then
    MsgBox sfol & " is not a valid folder/path.", vbInformation, "Invalid Source"
ElseIf Not fso.FolderExists(dfol) Then
    MsgBox dfol & " is not a valid folder/path.", vbInformation, "Invalid Destination"
Else
    fso.MoveFile (sfol & "\*.*"), dfol ' Change "\*.*" to "\*.xls" to move Excel Files only
End If
If Err.Number = 53 Then MsgBox "File not found"
End Sub

Copy ALL files (or of a specific file type) in one folder into another folder

CODE

Sub CopyFilesFolder2Folder()
Dim fso
Dim sfol As String, dfol As String
sfol = "c:\MyFolder" ' change to match the source folder path
dfol = "e:\MyFolder" ' change to match the destination folder path
Set fso = CreateObject("Scripting.FileSystemObject")
On Error Resume Next
If Not fso.FolderExists(sfol) Then
    MsgBox sfol & " is not a valid folder/path.", vbInformation, "Invalid Source"
ElseIf Not fso.FolderExists(dfol) Then
    MsgBox dfol & " is not a valid folder/path.", vbInformation, "Invalid Destination"
Else
    fso.CopyFile (sfol & "\*.*"), dfol ' Change "\*.*" to "\*.xls" to move Excel Files only
End If
If Err.Number = 53 Then MsgBox "File not found"
End Sub


I hope that you have found this informative and helpful!
