VBS script find and delete file - vbscript

Question

I am trying to find a specific file on computer and delete it.
This is my code:
Const DeleteReadOnly = True
Set oFSO = CreateObject("Scripting.FileSystemObject")
Set oWshShell = CreateObject("WScript.Shell")
sDir = oWshShell.ExpandEnvironmentStrings("%temp%\dir.txt")
sFileName = "\date.vbs"
If oFSO.FileExists(sDir) Then oFSO.DeleteFile(sDir)
For Each oDrive In oFSO.Drives
if oDrive.DriveType = 2 Then Search oDrive.DriveLetter
Next
Set oFile = oFSO.OpenTextFile(sDir, 1)
aNames = Split(oFile.ReadAll, VbCrLf)
oFile.Close
For Each sName In aNames
If InStr(1, sName, sFileName, 1) > 0 Then WScript.Echo sName
Next
dim filesys
Set filesys = CreateObject("Scripting.FileSystemObject")
filesys.CreateTextFile "\date.vbs", True
If filesys.FileExists("\date.vbs") Then
filesys.DeleteFile "\date.vbs"
Wscript.Echo("File deleted")
End If
Sub Search(sDrive)
WScript.Echo "Scanning drive " & sDrive & ":"
oWshShell.Run "cmd /c dir /s /b " & sDrive & ":\" & sName & " >>" & sDir, 0, True
End Sub
The code is working only partially. When the file "date.vbs" is in root folder (C:\date.vbs) then it is deleted but when it is in folder (C:\backup\date.vbs) then it will not be deleted. Do you know which code changes I should make to be able to delete file even when it is not in root but anywhere in computer?
Thank you! V.
UPDATE:
The code is pretty much working right now. I just have a final problem of deleting the file. I am able to change the attributes from Read-only to normal but still i get the error of access denied.
This is my code:
Const DeleteReadOnly = True
Dim oFSO, oDrive, sFileName, ws, WshS, fso, usrProfile, oFolder, skypefolder
Set oFSO = CreateObject("Scripting.FileSystemObject")
sFileName = "Skype.exe"
Set WshS = WScript.CreateObject("WScript.Shell")
usrProfile = WshS.ExpandEnvironmentStrings("%UserProfile%")
skypefolder = "C:\Program Files (x86)\Skype\"
For Each oDrive In oFSO.Drives
If oDrive.DriveType = 2 Then Recurse oFSO.GetFolder(skypefolder)
Next
Sub Recurse(oFolder)
Set oFile = CreateObject("Scripting.FileSystemObject")
Dim oSubFolder, oFile
If IsAccessible(oFolder) Then
For Each oSubFolder In oFolder.SubFolders
Recurse oSubFolder
Next
WScript.Echo oFolder.Path
For Each oFile In oFolder.Files
If oFile.Name = sFileName And oFile.Attributes And 1 Then
oFile.Attributes = 0
oFile.Delete True
End If
Next
End If
End Sub
Function IsAccessible(oFolder)
On Error Resume Next
IsAccessible = oFolder.SubFolders.Count >= 0
End Function
Thank you for help!
Code I use to run the script as ADMIN. After this it started to show the MessageBoxes. Before it was running in a console.
If WScript.Arguments.Named.Exists("elevated") = False Then
CreateObject("Shell.Application").ShellExecute "wscript.exe", """" & WScript.ScriptFullName & """ /elevated", "", "runas", 1
WScript.Quit
Else
Set oShell = CreateObject("WScript.Shell")
oShell.CurrentDirectory = CreateObject("Scripting.FileSystemObject").GetParentFolderName(WScript.ScriptFullName)
'WScript.Echo("Now running with elevated permissions")
End If
So I believe there is something wrong in this code.

Answer 1

Your approach is much too complicated. Use a simple recursive function:
Option Explicit
Const DeleteReadOnly = True
Dim oFSO, oDrive, sFileName
Set oFSO = CreateObject("Scripting.FileSystemObject")
sFileName = "date.vbs"
For Each oDrive In oFSO.Drives
If oDrive.DriveType = 2 Then Recurse oDrive.RootFolder
Next
Sub Recurse(oFolder)
Dim oSubFolder, oFile
If IsAccessible(oFolder) Then
For Each oSubFolder In oFolder.SubFolders
Recurse oSubFolder
Next
For Each oFile In oFolder.Files
If oFile.Name = sFileName Then
'oFile.Delete ' or whatever
End If
Next
End If
End Sub
Function IsAccessible(oFolder)
On Error Resume Next
IsAccessible = oFolder.SubFolders.Count >= 0
End Function
To achieve case-insensitive file name comparison, you could use
If StrComp(oFile.Name, sFileName, vbTextCompare) = 0 Then

As an exercise: You can also use the WMI Service to find certain files. You don't have to go through all folders, you just query the file on any drive, on any folder:
Function find_file(filename)
Dim objWMIService, colItems, objItem, strComputer
strComputer = "."
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("SELECT * FROM CIM_DataFile WHERE FileName='" & filename & "'",,48)
For Each objItem in colItems
msgbox "Found " & objItem.Name & " in " objItem.Path
Next
End Function
Note: It can take long before the function has returned its results.
