This is how you can create a text file in VB6

Dim iFileNo as Integer
iFileNo = FreeFile
'open the file for writing
Open "C:\Test.txt" For Output As #iFileNo
'please note, if this file already exists it will be overwritten!

'write some example text to the file
Print #iFileNo, "first line of text"
Print #iFileNo, " second line of text"
Print #iFileNo, "" 'blank line
Print #iFileNo, "some more text!"

'close the file (if you dont do this, you wont be able to open it again!)
Close #iFileNo

how large?

to keep it simple:

'1 form with:
'  1 textbox: name=Text1
'  1 command button: name=Command1
Option Explicit

Private Sub Command1_Click()
  Dim intFile As Integer
  Dim strFile As String
  strFile = "c:\temp\file.txt" 'the file you want to save to
  intFile = FreeFile
  Open strFile For Output As #intFile
    Print #intFile, Text1.Text 'the data you want to save
  Close #intFile
End Sub

this will replace the file each time you click the command button, if you want to add to the file then you can open "for append" instead of "for output"
