Renaming of lot of files and folders by using Ant Renamer

Ant renamer is a free and opensource program that makes easier the renaming of lots of files and folders by using specified settings.Ant renamer will only rename the files' names, it will not modify their contents.
It supports unicode, which means that you can rename files that have characters in Greek, Japanese, Chinese, Arab or any other language. Since most of the programs have problems with such names, it can be useful to be able to rename them to Latin (basic ASCII) characters for example.
