Add to folder name

[daveofgv]

I have a directory with a bunch of sub folders. I need to add a number and underscore to the main folder and all sub folders.

Example

Subfolder
Atmos_Energy

I need it to say
05_Atmos_Energy

There will be 500 subfolders

How would I have a form that can name all the subfolders at once?

Thanks

If you are trying to just rename each folder with x prefix, use something like this:

'Imports System.IO
Private Sub renameFolders(ByVal strRoot As String, ByVal prefixNumber As String)
        Dim subFolders() As String = Directory.GetDirectories(strRoot)
        For Each direct As String In subFolders
            My.Computer.FileSystem.RenameDirectory(direct, prefixNumber & "_" & direct)
        Next
        My.Computer.FileSystem.RenameDirectory(strRoot, prefixNumber & "_" & strRoot)
    End Sub

If you are trying to use some sort of number pattern, we will need some more info.

thanks for the reply.

No. I already have set nuimbers that every folder / subfolder will receive. I have to place certain files in a priority list and will have to go back and forth.

As for the code you offered - where do I put the filepath to the directory?

also - where would I add the number I want in front of the underscore (01, 02, 03 etc...)

I will mostly likely use a My.Setings for this, however, would like to ask about the above before I can see how I can make this work.

Hope this isn't too much to ask.

thanks in advanced

Example:

renameFolders("C:\New Folder1", "01")

 

[daveofgv]

So I first will have:

'Imports System.IO Private Sub renameFolders(ByVal strRoot As String, ByVal prefixNumber As String)         Dim subFolders() As String = Directory.GetDirectories(strRoot)         For Each direct As String In subFolders             My.Computer.FileSystem.RenameDirectory(direct, prefixNumber & "_" & direct)         Next        My.Computer.FileSystem.RenameDirectory(strRoot, prefixNumber & "_" & strRoot)     End Sub

and then:

renameFolders("C:\New Folder1", "01")

which I would place where?

thanks

 

[Joshdbr]

You would place the bottom code wherever you would like to rename to folders. You will want to place the Imports System.IO on the very top of the code. Example:

Imports System.IO
Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim rootFolderPath As String = "C:\New Folder1"
        Dim numberPrefix As String = "01"
        renameFolders(rootFolderPath, numberPrefix)
    End Sub

    Private Sub renameFolders(ByVal strRoot As String, ByVal prefixNumber As String)
        Dim subFolders() As String = Directory.GetDirectories(strRoot)
        For Each direct As String In subFolders
            My.Computer.FileSystem.RenameDirectory(direct, prefixNumber & "_" & direct)
        Next
        My.Computer.FileSystem.RenameDirectory(strRoot, prefixNumber & "_" & strRoot)
    End Sub
End Class

There is an error while debugging:

Argument "newName" must be a name, and not a relative or absolute path:
'01_C:\Users\dave\Desktop\test_rename\test_rename_01'. Parameter name: newName

The line it is refering to is:

My.Computer.FileSystem.RenameDirectory(direct, prefixNumber & "_" & direct)

Any suggestions?

thanks

[Joshdbr]

Sorry, change that line to this:

My.Computer.FileSystem.RenameDirectory(direct, prefixNumber & "_" & direct.Substring(direct.LastIndexOf("\")).Replace("\", ""))

 

[JohnH]

Dim path = "c:\some\sub\folder"        
Dim newname = "01_" & IO.Path.GetFileName(path)
My.Computer.FileSystem.RenameDirectory(path, newname)

 

[daveofgv]

Joshdbr - thanks for all your hard effort

JohnH - this appears to only change the folder name that I choose - not all the subfolders within that directory as well?

If I have "c:\newfolder

and within the newfolder - there are 500 folders

I will need "newfolder" and all 500 folders changed to have the _01 as a prefix.

Am I doing something wrong?

Thanks in advanced

[Joshdbr]

Using JohnH's code:

Imports System.IO
Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim rootFolderPath As String = "C:\New Folder1"
        Dim numberPrefix As String = "01_"
        renameFolders(rootFolderPath, numberPrefix)
    End Sub
 
    Private Sub renameFolders(ByVal strRoot As String, ByVal prefixNumber As String)
        Dim subFolders() As String = Directory.GetDirectories(strRoot)
        For Each direct As String In subFolders
            Dim newname = prefixNumber & IO.Path.GetFileName(direct)
            My.Computer.FileSystem.RenameDirectory(direct, newname)
        Next
        Dim newname = prefixNumber & IO.Path.GetFileName(strRoot)
        My.Computer.FileSystem.RenameDirectory(strRoot, prefixNumber & newName)
    End Sub
End Class

 

[daveofgv]

yea, that's what I did, however, I will have to check again - since it's only naming the first folder.

As usual (with me) operator's error somewhere. lol

 

[daveofgv]

then where does these declarations go?

Dim path = "c:\some\sub\folder"        
Dim newname = "01_" & IO.Path.GetFileName(path)

thanks

daveofgv

 

[Joshdbr]

Wherever you want to rename the folders

 

[daveofgv]

LOL. I understand that.

However, you had : Using JohnH's code

Imports System.IO Public Class Form1     
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load       
  Dim rootFolderPath As String = "C:\New Folder1"        
Dim numberPrefix As String = "01_"        
renameFolders(rootFolderPath, numberPrefix)     
End Sub       
Private Sub renameFolders(ByVal strRoot As String, ByVal prefixNumber As String)         
Dim subFolders() As String = Directory.GetDirectories(strRoot)         
For Each direct As String In subFolders             
Dim newname = prefixNumber & IO.Path.GetFileName(direct)             
My.Computer.FileSystem.RenameDirectory(direct, newname)         
Next        
Dim newname = prefixNumber & IO.Path.GetFileName(strRoot)         
My.Computer.FileSystem.RenameDirectory(strRoot, prefixNumber & newName)    
 End Sub
End Class

But don't mention those declarations.

That's why I was asking.

I keep getting an error that says

Variable 'newname' hides a variable in an enclosing block

And also, I am seeing the Form1_Load event has
"numberPrefix as string"
however,
in Private Sub renameFolders
you have
"prefixNumber"

May I ask why the difference?

Sorry about the confusion
