Idea - part open very big file

[Radik Komissaroff]

Idea - part open very big file, example sql dump 20 GB or XML.
Now it’s impossible.
In C# it make code
const int MAXCHAR = 1000;
char[]symbols;
string path = @“E:\Downloads\fias_xml\AS_HOUSE_20170521_ca856fdd-35aa-4528-a362-57e96fa44a39.XML”;//big file 28 GB
BinaryReader breader = new BinaryReader(File.OpenRead(path));
symbols = breader.ReadChars(MAXCHAR);
