f is a String!  You cannot close a String.

From your recent postings I conclude that you mean "opened by another
process".  No, you cannot close a file from another process without
going through major operating system specific tricks (on Windows there
is ProcessExplorer of former Sysinternals for example).  You also
usually need specific privileges, i.e. have root rights on a *nix
system and have administrative permissions on a Windows box.

Kind regards
