So I want to attach some secret info to my files in a program, and VS2013 throws an exception stating:
An unhandled exception of type 'System.NotSupportedException' occurred in mscorlib.dll Additional information: The specified path format is not supported.
For the lines:
string metafile = filename + ":key"; StreamWriter metadata = new StreamWriter(metafile);
How can I solve this? I need it, because this way I can check it with console with the command: "notepad file.txt:key".
