    i want to break a large file into smaller files each of size 2KB.i want to give the file names as 1.txt,2.txt,3.txt etc how can i do this

    In general 1 KB is about 1024 characters. What you can do is get every 2048 characters from the main file and then save that data into a new file, using an index variable to count how many files have been made and name the file that.

    Try something like this, you will have to format the outout to the files and play around with the number of characters in each text file:

    Private Sub Command1_Click()

    'Path/filename of original file
    Open "C:/break/original.txt" For Input As #1

    Dim intLength As Double         'Length of files
    Dim intCounter As Integer       'Counter for unique filenames
    Dim strLine As String              'One line from master file
    Dim strOutput As String          'Line of output

    'reset vars
    intLength = 0
    intCounter = 1
    strOutput = ""

    'Loop till EOF(master)
    While Not EOF(1)
        'Get next line
        Line Input #1, strLine
        strOutput = strOutput & strLine
        'record length of line
        intLength = intLength & Len(strLine)
        If intLength > 1024 Then

            'If number of characters in output file exceeds a certain number then produce output
            Open "C:/break/" & intCounter & ".txt" For Output As #2
            Print #2, strOutput
            Close #2

            'Reset vars
            intLength = 0
            intCounter = intCounter + 1
            strOutput = ""
        End If
    End Sub
