C# Moved file without specifying path

Question

I just ran

File.Move(@"C:\sub1\file.xml", "file" + ".XMl"));

The file did dissappear from C:\sub1. No error was thrown. Did the file go somewhere?

Answer 1

When directory is not specified, current one is used:

The sourceFileName and destFileName arguments can include relative or absolute path information. Relative path information is interpreted as relative to the current working directory. To obtain the current working directory, see GetCurrentDirectory.

  Environment.CurrentDirectory = @"C:\Test";

  // C:\sub1\file.xml will be moved to C:\Test\file.XMl 
  File.Move(@"C:\sub1\file.xml", "file" + ".XMl"));

Answer 2

It moved to the app working directory. Usually it is where executable file located
