reating "custom" file attributes is not allowed.

You can only set one of the FileAttributes .

Example:

File.SetAttributes(@"C:\myfile.txt", FileAttributes.Hidden);

The attributes you can change here are the NTFS attributes. Details here: http://msdn.microsoft.com/en-us/library/system.io.fileattributes%28v=vs.110%29.aspx

Version is a resource embedded in an executable file. A similar question was asked here: How do I set the version information for an existing .exe, .dll?

You're probably struggling because you can't add arbitrary information into a file. There are a known set of attributes you can change using the FileAttribute properties

What you would normally do is provide some information at the start of your file, typically called the file header. This then allows a custom reading implementation to read out the version, without having to read the rest of the file. This is quite standard practise with all the files you're used to, for example a WAV audio file:
