Well, after a long break, I've begun a new program: NameEx. Basically, it's for batch renaming. It can do simple sequence renaming, as well as more complex functions, changing file extensions, or making renamed copies. Expect a beta soon.
That sounds very interesting. I have wanted to rename a bunch of files in my back up download list, renaming one by one takes FOREVER when I have to do it to a hundred so files.
