Have you ever needed to modify the file names of a large number of files but didn't want to rename all of the files the same name? Wanted to do a simple search/replace on a portion of various file names? Wanted to perform a regular expression rename on multiple items?

PowerRename is a Windows Shell Context Menu Extension for advanced bulk renaming using simple search and replace or more powerful regular expression matching. While you type in the search and replace input fields, the preview area will show what the items will be renamed to. You can toggle specific items to include or exclude from the operation in the preview area. Other checkbox options allow more control of scope of the rename operation. PowerRename then calls into the Windows Explorer file operations engine to perform the rename. This has the benefit of allowing the rename operation to be undone after PowerRename exits. PowerRename was designed to cover the majority of bulk rename scenarios while still striving for simplicity for the average user.
