Krename is a very powerful batch file renamer for KDE which can rename a list of files based on a set of expressions. It can copy/move the files to another directory or simply rename the input files. Krename supports many conversion operations, including conversion of a filename to lowercase or to uppercase, conversion of the first letter of every word to uppercase, adding numbers to filenames, finding and replacing parts of the filename, and many more. It can also change access and modification dates, permissions, and file ownership.
