I know Atom is an editor and as such the issue I got is not really a problem but I thought you might want to know about it just the same. I tried to open a very huge csv file (211 029 247 characters over 1 591 889 lines) and I was quite happy to see Atom warning me that opening huge files might make Atom unresponsive for a while. But then it crashed. As I said, not a big deal, but notepad and notepad++ were able to open it in no time. Similarly, Komodo could not and neither Excel.
