WildRename is a multi-file renaming application for Microsoft Windows users.
Its very simple user interface helps you build and perform many file renaming operations one-by-one or in batches.
In brief, WildRename helps you:
• convert filenames to lower/upper case or normalise case (Capitalize First Letter)
• add or remove strings of characters from filenames
• replace strings of characters in filenames, using either simple replacements or powerful regular expressions
• add text counters to a series of files (e.g. 0001_filename.ext)
