Change file names in a folder



Hi to all
I am trying to change the names of all the files in a folder by putting a
new month and year at the end of each file name using the following code:
Dim f as String, s as String
Const Dest = "C:\Mis documentos\12 December 2005\"
f = dir(Dest & "*.*")
do while f <> ""
s = Mid(f, 1, (Len(f) - 9)) & _
Format(DateSerial(Year(Date), Month(Date) - 1, 1), "yyyy-mm")
Name Dest & f As Dest & s
f = dir()
It gets stuck in the following code:
Name Dest & f As Dest & s
Then I tried:
Name f As s
It Didn´t work. then I tried:
Name f As Dir(Dest & s)
It didn´t work
The message keeps on saying that it cannot find the root directory access.
Any solutions or ideas? It would be appreciated.






Try this code...

Function GetAllFilesInDir(ByVal strDirPath As String) As Variant
' Loop through the directory specified in strDirPath and save each
' file name in an array, then return that array to the calling
' procedure.
' Return False if strDirPath is not a valid directory.
Dim strTempName As String
Dim varFiles() As Variant
Dim lngFileCount As Long

On Error GoTo GetAllFiles_Err

' Make sure that strDirPath ends with a "\" character.
If Right$(strDirPath, 1) <> "\" Then
strDirPath = strDirPath & "\"
End If

' Make sure strDirPath is a directory.
If GetAttr(strDirPath) = vbDirectory Then
strTempName = Dir(strDirPath, vbDirectory)
Do Until Len(strTempName) = 0
' Exclude ".", "..".
If (strTempName <> ".") And (strTempName <> "..") Then
' Make sure we do not have a sub-directory name.
If (GetAttr(strDirPath & strTempName) _
And vbDirectory) <> vbDirectory Then
' Increase the size of the array
' to accommodate the found filename
' and add the filename to the array.
ReDim Preserve varFiles(lngFileCount)
varFiles(lngFileCount) = strTempName
lngFileCount = lngFileCount + 1
End If
End If
' Use the Dir function to find the next filename.
strTempName = Dir()
' Return the array of found files.
GetAllFilesInDir = varFiles
End If
Exit Function
GetAllFilesInDir = False
Resume GetAllFiles_End
End Function

Sub RenameFiles()
Dim varFiles As Variant
Dim i As Integer
Dim strFileNameOld, strFileNameNew, strDate
Dim strDir As String

'change this to your dir
strDir = "C:\Mis documentos\12 December 2005\"

'Calls the above function
varFiles = GetAllFilesInDir(strDir)

' from zero to the size of hte array (which now contains all files in
the directory)
For i = 0 To UBound(varFiles)
' date
strDate = Format(DateSerial(Year(Date), Month(Date) - 1, 1),
strFileNameOld = strDir & varFiles(i)
' new file name with the file suffix (e.g. .xls) reappeneded
strFileNameNew = strDir & Left(varFiles(i), Len(varFiles(i)) - 4) &
strDate & Right(varFiles(i), 4)
Name strFileNameOld As strFileNameNew
Next i

End Sub
