You could create a buffer for this purpose. Here is some code to get you started. (I don't have vb6 at this moment so the code is not verified)

Example Code:

Dim Buffer As String * 1000
Open "C:\Windows\FileName.txt" For Binary As #1
Get #1, 1, Data   
Close #1

Moreover in your case you will need to keep track of the position in the file

Get #file handle, position, Buffer

Also use Put to write the read buffer to another file.

Put #file handle, position, Buffer

This tutorial covers how to read and write from binary files, there is a section about reading blocks of data from a file.
