spacetornado Renamer 1.1 Publisher's Description

Mass rename hundreds or thousands of files in batches by using Search and Replace, Remove Characters, Change Case and Add Text -- all for free.
You can change the case to First Letter Capital (also called Title Case), and even skip words like "to", "the", and "a" to prevent them from being renamed to First Letter Capital case.
Other features include: undo the last rename operation, preview results before renaming, perform successive rename operations on the renamed files by clicking the "up arrow" button, perform multiple rename operations at once (you choose the order), redirect (copy) the renamed files to a separate folder, advanced "File Exists" functionality, drag and drop support, rename status information, and more.
