Renaming Script

I have a ton of mp3 files in different folders which are in the format below;

Track # - Song Name (Artist Name).mp3
ex. 01 - La Fille De Pekin (Frederick Rousseau).mp3

I wanted to rename all the files so I could import them easily using the following format;

Track # - Artist Name - Song Name.mp3
ex. 01 - Frederick Rousseau - La Fille De Pekin.mp3

This format helps me to adjust the meta data while importing. I wrote the following VBScript to rename the files in a directory :D

Option Explicit
On Error Resume Next

Dim a: a = WScript.Arguments.item(0)
Dim fso: Set fso=CreateObject("Scripting.FileSystemObject")
Dim lFolder: Set lFolder = fso.GetFolder(a)
Dim lFiles: Set lFiles = lFolder.Files
Dim lFile, numFiles
numFiles = 0
For each lFile in lFiles
  RenameFile(lFile)
Next

Function RenameFile(fileObject)
  Dim oldName, newName, fullnewName
  Dim posDash, posParOpen, posParClose
  Dim artistName, songName, trackNum

  oldName = fileObject.Name
  'get location of the dash
  posDash = InStr(oldName, "-")
  'get location of the first (
  posParOpen = InStrRev(oldName,"(")
  'get location of last )
  posParClose = InStrRev(oldName, ")")

  'get the track number
  trackNum = Mid(oldName,1,posDash)
  trackNum = Replace(trackNum,"-","")
  trackNum = trim(trackNum)

  'get the song name
  songName = Mid(oldName,posDash,Cint(posParOpen - PosDash))
  songName = Replace(songName,"-","")
  songName = Trim(songName)

  'get the artist name
  artistName = Mid(oldName,posParOpen,Cint(posParClose - PosParOpen))
  artistName = Replace(artistName,"(","")
  artistName = Trim(artistName)

  'new name formatted
  newName = trackNum & " - " & artistName & " - " & songName & ".mp3"
  fullNewName = fileObject.ParentFolder & "\" & newName

  WSCript.Echo
  WScript.Echo "Renaming.. " & fileObject.Name
  WScript.Echo "To........ " & newName
    'comment the following line to test it only.
    fileObject.Move fullNewName
  WScript.Echo
  numFiles = numFiles + 1
End Function


WScript.Echo "Total Files Modified: " & numFiles
Set fso = Nothing
Set lFolder = Nothing
Set lFiles = Nothing

All you have to do to use it is copy paste into a vbs file "reformat.vbs" for example. Then run it using the command line:

C:\> cscript reformat.vbs "C:\Music\Some Messed up Album\"

Here is a link to the script, if you wish to download it. Just rename the file.
Link: Reformat.txt

Multi Variable Batch

This is a great example for reading lines through a regular batch file and processing the input at tokens.

Lets say for example you have a file with the following input:

user1 homedir1
user1 homedir2

etc

If you want to, you could add this to your batch file;

for /f "tokens=1*" %%i in (filename.txt) do @echo %%j\%%i

Notice that %%j was not defined, but is automatically assigned a value alphabetically. The output will look something like;

homedir1\user1
homedir2\user2
