Careful with that approach. Loading a 1+ GB file may take quite some time. Even with Wndows Notepad, very large files take quite awhile to load. I think a better, much harder, approach would be to create a paging system for large files, i.e., chunk-type reader. Many here have probably created their own "huge file reader" applications in the past & if interested, may want to pose a few questions along that line of thought
