I moved this topic from The Lounge, since it is Common Lisp (Lispworks) specific.

If you have to ask about "lisp's functions to manipulate file" then it is likely your knowledge of the language would require more explanation that would make sense in a forum post. There are very good free online books about Common Lisp available, like Practical Common Lisp.

Lispworks also has quite good, if proprietary, GUI library, if that is you mean. It is described in Lispworks documentation under CAPI documents.
