How To

Add the files through the GUI or drag and drop files directly onto the App. These original filenames show up in the Original Filename column. Grayed out rows indicate files that you do not have permissions to change.
Next select how to change the file names:
  • Replace First Occurrence
  • Replace Last Occurrence
  • Replace All Occurrences
  • Wildcard
  • Append
  • Prepend
  • Date
  • Sequence
  • Character Removal
  • Regular Expression
  • Change Case
As text is entered into the appropriate text fields the resulting filenames appear in the Renamed Filename column. As you type each row is updated to reflect the changes you will make.
Finally click the Rename button, and all your files will be renamed as displayed. You will be informed of any files that could not be modified.

Need more options renaming your files? Open the options pallet by clicking the Options button. From here you can hide the file extensions, ignore case, force uniqueness of resulting names or change the checked and selected files.
The checkbox to the left of each row allows you to choose which files will be renamed. This allows you to pull in a number of files once and rename subsets as you wish, without constantly adding and removing files. If the box is checked, the file will be changed, otherwise the file will go unaltered.
Hiding the extensions is often useful when you need to append something to the end of the filename, but not alter the file extension. Check the ‘Hide Extensions’ checkbox and rename as desired.
The Image Browser makes renaming pictures even simpler by allowing visual naming and reordering.
