Hi All,

Any update as to when the function described in the below ticked would be action-ed, I am more interested in isBinary (check a file whether is is binary file or not)

Those are totally different ideas.

When writing a file, some operating systems support line ending conversion. To do that, you explicitly specify that you are writing to a text file. Then a "binary file" is just any file that is not a text file. However, this is merely a conversion process on writing. You cannot discover whether a file is a binary file in reverse. At most you can check whether you yourself opened the file as a binary file.

I tried to write the below code but it always return's as binary for any file type, please point me what is wrong in the below program

void main () {
import std.stdio: writeln, File;
string fn = "C:\\temp\\test.txt";
//string fn = "C:\\WINDOWS\\system32\\whoami.exe";
File f;
f.open(fn, "rb");
if(f.isOpen) { writeln("BinaryFile"); } else { writeln("NotBinaryFile"); }
f.close();
}
