Import several txt files into separate sheets within 1 workbook

[Steve]

Hi everyone. I have a folder that receives data dumps from a
different system. The files are text files, contain data on only 1
sheet, are very large, and the names of the files are generated from
the other system.

I have code (from the newsgroup - thanks!) that enables me to select
the files to be imported:

Sub Combine()

Dim GetFiles As Variant
Dim iFiles As Long
Dim nFiles As Long
GetFiles = Application.GetOpenFilename _
(FileFilter:="Text Files (*.*),*.*", _
Title:="Select Files To Open", MultiSelect:=True)
If TypeName(GetFiles) = "Boolean" Then
''' GetFiles is False if GetOpenFileName is Canceled
MsgBox "No Files Selected", vbOKOnly, "Nothing Selected"
End
Else
''' GetFiles is Array of Strings (File Names)
''' File names include Path
nFiles = UBound(GetFiles)
For iFiles = 1 To nFiles
'' List Files in Immediate Window
Debug.Print GetFiles(iFiles)
Next
End If
End Sub

But now I don't know how to copy the data into a seperate worksheet
within the same workbook.

So basically, I'd like to choose and consolidate multiple text files
into 1 excel workbook containing many worksheets.

I have very limited knowledge of VBA. Thanks so much!!
