You used forward slashes rather than backslahes, resulting in:

try
{
    System.IO.File.Delete(@"‪C:\Projets\Prj.zip");
}
catch { }

It seems some odd character has slipped in somewhere making it invalid. If I copy/paste the line above, it gives me the same exception. However, if I remove the string and type it in by hand, it will give me a FileNotFound (obviously).

Try cop/pasting this line:

System.IO.File.Delete(@"C:\Projets\Prj.zip");

After further investigation, the culprit appears to be a invsible character between the " and the C. Specifically, the unicode character for "left to right embedding" is present. If I convert the string to unicode, you can clearly see it:

System.IO.File.Delete(@"‪C:\Projets\Prj.zip");

Use Path library, to access platform independent path manipulation. Example is given below:

var root = "C:" + Path.DirectorySeparatorChar;

var path = Path.Combine( root, "Projects", "Prj.zip" );

File.Delete(path); //will try to delete C:\Projects\Prj.zip

Try

 string file = @"‪C:\Projets\Prj.zip";
  if( System.IO.File.Exists(file))
    System.IO.File.Delete(file);

File paths in Windows use backslashes, not forward slashes:

System.IO.File.Delete(@"C:\Projets\Prj.zip");
