Work the way that suits you best

Alternatively you can use it straight from the Windows Explorer by right-clicking the files and selecting the "Better File Rename..." menu item.

Bulk processing options

Separate processing for file names and file extensions
Process files, folders and subfolders ("recursively")
Choose to confirm each file name or batch process them automatically

Combine multiple rename steps

You can combine several rename actions into a single multi-step rename. This allows you to perform even the most complex batch renaming jobs in a single pass.

Better File Rename allows you to create as many rename steps as you require and lets you edit and re-arrange them at will.
