A filename editor that puts the fun back into organizing the file system.

When 10, 50, 100 or even more files have to be renamed then using the OS-X Finder quickly becomes tedious at best.

This Filename Editor solves this problem in a unique way. Edit at leisure but quick and efficient. Using editing commands that work on multiple lines simultaneously. Insert tags read from the file itself. And once satisfied with the result, commit all changes at once. It is even possible to interrupt the session and continue at a later point in time.

Filename Editor solves the problem that batch-renaming utilities have: sometimes the batch processor relies on faulty or missing data, and there is no way of inspecting/correcting this data before committing the changes. Possibly losing valuable information in the process.

Still Filename Editor keeps the best feature of batch processors: copying data from the file contents (tags) into the filename quickly and efficiently for all filenames at once. However with Filename Editor it is possible to actually see and verify the changes before committing them.

To prevent unexpected results from occurring, there is a status column that informs about potential problems like duplicate naming or renaming a file to an existing one.

Give it a try, you will quickly discover that you cannot do without…


  • Multi line editing (insert, delete, copy, paste etc).
  • Status column to detect naming conflicts.
  • Use regular expressions for selections (live screen updates while typing the expression).
  • Read & Insert tag values from: MP3, Flac and Tiff files.
  • Renaming can be performed in multiple sessions. I.e. you can quit & resume the app without losing information.
  • Insert an auto-incrementing number in multiple lines. Using leading zero’s if required.
  • Undo/redo support.
  • Available from the ‘services’ menu.
  • Drag & drop supported.
  • Remembers file access rights between sessions.
  • Built-in & on-line help

It shows the following columns:

  • The original name of the file (not editable).
  • The new name, this column is editable.
  • The file extension (also editable).
  • The status column (not editable).

The non-editable columns can be used as the source for a copy & paste operation.

The next screenshot shows the “File Tag” column, and the work in progress to change the original name into something new. Notice that the original names are no longer in-sequence as the track number has been used to (manually) reorder the files for the next operation.

The next screenshot shows the setting of the auto-number to be inserted at all cursor positions and in all selections.

The next screenshot shows the completion of the renaming where in the last step the title tag was copied to the new name. The next step would be to click the ‘commit’ button to actually write the new names to the files.
