KiranAlamuru&nbsp;I've used this snipped before for similar purposes. I've tested it with your requirements and should be good.&nbsp;&nbsp;$FileFolder    = "S:\--106-- Downloads\"
$FileName      = "enwiki-20110115-abstract6"
$FileExt       = "xml"
$LimitSize     = 2MB
$FilePath      = $FileFolder + $FileName + '.' + $FileExt
$ReadFile      = [io.file]::OpenRead($FilePath)
$Size          = new-object byte[] $LimitSize

$RemainingData = 0 
$ID            = 0
Do 
 {
  $RemainingData = $ReadFile.Read($Size, 0 , $Size.Length)
  If($RemainingData -gt 0) 
   {
    $NewChunk  = $FileFolder + $FileName + "-$ID-" + '.' + $FileExt
    $ChunkFile = [io.file]::OpenWrite($NewChunk)
    $ChunkFile.Write($Size, 0 , $RemainingData)
    $ChunkFile.Close()
    }
  $ID ++
 }While($RemainingData -gt 0)

$ReadFile.Close()

Erick A. Moreno R.&nbsp;Thanks, it seems a good script to split a large file into multiple 2 MB files however it cannot keep the XML structure intact and in the end, you will get many broken XML files.Best,&nbsp;
