first of all, how do you define "duplicates" ? which columns are used for comparison?
Ryan ChongCommented:
if you wish to compare all 5 columns to identify the duplicate entries, you probably can use CountIFS formula for identification.

For example, in Cell F2, put in formula:

Open in new window

and drag down the formula accordingly.

By using this formula, you will find the count of occurrence per item. If the value is greater than 1 then it's identified as duplicate.

to copy the duplicate rows to another sheet, you probably need this:
Sub copyDupRows()
    Dim lastRow As Long
    Dim r As Range
    Dim ws As Worksheet
    Application.ScreenUpdating = False
    Application.EnableEvents = False
    ActiveSheet.Copy After:=Sheets(Sheets.Count)
    Set ws = Sheets(Sheets.Count)
    lastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row
    ws.Range("$F$2:$F$" & lastRow).Cells.FormulaR1C1 = _
    ws.Range("$A$1:$F$" & lastRow).AutoFilter Field:=6, Criteria1:="=1", _
        Operator:=xlOr, Criteria2:="="
    Set r = ws.Range("A2:A" & lastRow).SpecialCells(xlCellTypeVisible)
    ws.AutoFilterMode = False
    Application.EnableEvents = True
    Application.ScreenUpdating = True
End Sub

Open in new window

Hey Ryan,

It seems that we are comparing two sets of rows each time...
Can we get it to highlight the duplicate..?

Also, your final subset has only "four" lines.. on the new sheet .  What are those..?  Thx

To highlight the duplicate entries, you probably can use Conditional Formatting with following formula:
