Recently I faced an issue while preparing data for my performance testing. I need to edit huge files which has 300K rows of records which consumes 1.6GB of my hard disk.
Initially I tried to open that file using Notepad. But it was not able to open, due to its large file size. Later I tried with Wordpad. I was able to open, but I couldn’t edit in text file. It was hanging even for one click. Later I found below text editors which helps you to open large files quickly
