The exception is thrown here:

     version(Windows)
     {
         alias TypeTuple!(GENERIC_READ,
                 FILE_SHARE_READ, (SECURITY_ATTRIBUTES*).init,

         cenforce(h != INVALID_HANDLE_VALUE, name);    // <-- HERE

It seems to be related to a Unicode encoding issue, possibly the 
encoding that the console is using. (I am assuming that getfilename() 
reads from the console.)

It could be about file access rights as well.

Try to declutter your code as much as possible, then print the 
file name before trying to call File, and take a look at what's 
inside that string. This is not a solution, but it's a start.

Am I right with it's place? I get to console only some crap.

After a call to readln, the string returned has termination characters 
that need to be stripped off.

import std.stdio;
import std.file;

void main()
{
	string name = readln();

	while(name[$-1] == '\x0a' || name[$-1] == '\x0d')
		name.length -= 1;

	if(name.exists)
		writeln(name, " exists!");
	else
	{
		writeln(name, " doesn't exists!");
		return;
	}

	auto filearray = cast(char[]) read(name);
	writeln("\n", filearray);
}

Good call.

 	string name = readln();

 	while(name[$-1] == '\x0a' || name[$-1] == '\x0d')
 		name.length -= 1;

Or with std.string.chomp:

     string name = chomp(readln());
