Use this
Declare

Private Declare Function GetLogicalDriveStrings Lib "kernel32" Alias "GetLogicalDriveStringsA" (ByVal nBufferLength As Long, ByVal lpBuffer As String) As Long
Private Declare Function WNetGetConnection Lib "mpr.dll" Alias "WNetGetConnectionA" (ByVal lpszLocalName As String, ByVal lpszRemoteName As String, cbRemoteName As Long) As Long
Private Declare Function SearchTreeForFile Lib "imagehlp" (ByVal RootPath As String, ByVal InputPathName As String, ByVal OutputPathBuffer As String) As Long
Private Declare Function GetDriveType Lib "kernel32" Alias "GetDriveTypeA" (ByVal nDrive As String) As Long
Private Const MAX_PATH = 260
Private Const DRIVE_CDROM = 5
Private Const DRIVE_FIXED = 3

Call this

Private Function Find_File(FileName As String) As String
 Dim tempStr As String
 Dim Ret As Long
 Dim AllDrives As String
 Dim DriveArray
 Dim lErrCode As Long
 Dim Counter As Long
 Dim szValueName As String
 Dim sUNCName As String
 
   AllDrives = String(255, Chr$(0))
   Ret = GetLogicalDriveStrings(255, AllDrives)
   AllDrives = Replace(AllDrives, Chr$(0), "")
   AllDrives = Replace(AllDrives, "\", "\,")
   DriveArray = Split(AllDrives, ",")
 
 For Counter = 0 To UBound(DriveArray) - 1
 Ret = GetDriveType(DriveArray(Counter))
 
  If GetDriveType(DriveArray(Counter)) = DRIVE_FIXED Then
 
 
 
 
   'create a buffer string
   tempStr = String(MAX_PATH, 0)
   
   'returns 1 when successfull, 0 when failed
   Ret = SearchTreeForFile(DriveArray(Counter), FileName, tempStr)
   
   If Ret <> 0 Then
       Find_File = Left$(tempStr, InStr(1, tempStr, Chr$(0)) - 1)
       Exit Function
   End If
   
  End If
   
 Next Counter
 
 Find_File = "NOT FOUND"
End Function

This works to locate any filename or file pattern:

'---
strFilename = "file to find.txt" ' patterns can also be used
Shell("command /c dir " & strFilename & " /s/b > C:\myfile.txt")
'---

(If using NT/2000/XP, replace "command" with "cmd".)

The result will be a file, myfile.txt, which contains all occurrences of the file you requested.  Once created, you can open the file and you'll see a list of the file(s) you were searching for.

Take a look here for different ways with which you can find a file:-
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q185476

Once you find the file, using one of the above mentioned mechanisms, you can open the file to modify the contents using the following lines of code:-

  Const ForReading = 1
  Const ForWriting = 2
  Const ForAppending = 8
  Dim fso As Object
  Dim f As Object

  Set fso = CreateObject("Scripting.FileSystemObject")
  Set f = fso.OpenTextFile("c:\test.txt", ForWriting, True)
  f.Write "Text Modified"
  f.Close

  Set f = Nothing
  Set fso = Nothing
