Minor Description
Howdy,
org.apache.commons.io.FileUtils#moveFile(File, File) currently throws an IOException if the destination File already exists. IMHO this is the expected behavior in cases where the destination file has is at least one byte in size. But in some cases the user might want to create a file before calling this method to be sure it was created successfully and use another filename if not. Since a generic IOException is thrown in cases where the destination file does already exist a user not able to implement counter-measures for such cases. So i suggest to add another method for this case.
