The following are some of the proposed ideas and tasks for commons-io:

• A proper user guide
• A URLUtils class that has many of the FileUtils operations, but for a URL
• FilePoller for telling when a file changes. Look in Tomcat, or GenJava[bayard] (One implemented in bugzilla awaiting investigation)
• A "hot folder" handler which triggers an action when a new file has been uploaded to an FTP directory, for example.
• JoinReader/ConcatReader. One in GenJava, one submitted to Bayard
• FormattedWriter, when it writes out values it uses Format objects to output them.
• FixedWidthReader. Reads in files with a known width, ie) mainframe like.
