Do you want to *recursively* list all files in the directory? If so, take a look at `file-seq': http://clojuredocs.org/clojure_core/clojure.core/file-seq Passed a java.io.File pointing to a directory, it gives you a sequence of file objects in it and all its subdirectories. To get a list of all files ending in .jar in the current directory: (filter #(.endsWith (str %) ".jar") (file-seq (java.io.File. "."))) -- Moritz Ulrich
