Hi,

The standard library module Directory contains

    doesFileExist :: FilePath -> IO Bool

See http://www.haskell.org/onlinelibrary/directory.html

Regards,
Thomas Hallgren

PS If using doesFileExist is a bad idea, then using some of the other 
functions from the module Directory, e.g. getDirectoryContents, is 
probablya bad idea too...
