[Commons IO] File splitting and joining
I am looking for a file splitter and joiner and naturally looked at
commons-io to see if it had it, but it doesn't look like it does. Would it
make sense to add it to FileUtils or something? Should be somewhat simple
to implement.

Hmmm. The JDK already comes with the widely unknown SequenceInputStream. However, an overloaded cop method has something appealing ;-)

Henri,
The copy() method sounds good.
For split, maybe something like: split(File and/or InputStream, long
bytesPerChunk, NamingScheme);
Where NamingScheme is an interface that would define how the chunks should
be named, for example, an IncrementingNamingScheme would append a number to
a name for each chunk. Same naming scheme class would be used for the
reverse process too.

Or maybe for the join it's a IOUtils.copy(InputStream[], OutputStream)
and Reader[] overload.
How would split look? Split on byte number for splitter and on line
number for Reader?
