I want to use the Session.SessionID as file name and query string in URL. I want to know if its format is suitable for these applications. For example you can not use '?' or '<' characters in a file name.

Is SessionID format string safe for file names and query strings?

    From this MSDN link

    "The ASP.NET session identifier is a randomly generated number encoded into a 
 24-character string consisting of lowercase characters from a to z and numbers 
 from 0 to 5."

    So the answer is, Yes & it’s safe to be used for file names and query strings
