Editing APS Shortener

= Disklavier File Renamer =

== Overview ==
The '''Disklavier File Renamer''' is a tool designed to shorten filenames for early Yamaha Disklaviers, which only support the '''DOS 8.3''' filename format. This format restricts filenames to '''eight characters''' followed by a '''three-character extension''' (e.g., <code>00SONG01.MID</code>). Since modern computers allow much longer filenames, this program ensures your files are properly renamed for compatibility.

The software provides a '''simple drag-and-drop interface''' for quick renaming and ensures that original files remain untouched by creating shortened copies.

== Features ==
* '''Automatic Filename Shortening:''' Converts long filenames into the '''8.3 format''' required by early Disklaviers.
* '''Drag-and-Drop Simplicity:''' No need for complex settings—just drop your files into the window.
* '''File Collision Handling:''' If a filename conflict occurs, you can choose to:
** Overwrite the existing file.
** Increment the filename to keep all versions.
** Cancel the renaming process for that file.
* '''Preserves Original Files:''' The program creates a copy with the new name, leaving the original unchanged.
* '''Persistent Settings:''' Remembers your preferences (e.g., overwrite behavior) between sessions.

== How to Use ==
=== 1. Open the Program ===
Launch the '''Disklavier File Renamer''' on your computer.

=== 2. Drag and Drop Your Files ===
* Drag MIDI or Disklavier-related files (<code>.mid</code>, <code>.midi</code>, <code>.fil</code>) onto the program window.
* The program will automatically detect and process them.

=== 3. Choose Your File Handling Option ===
* The program includes a checkbox labeled '''"Overwrite Duplicate Files"''':
** If checked, files with duplicate names will be overwritten.
** If unchecked, filenames will be automatically incremented (e.g., <code>00SONG01.MID</code>, <code>01SONG01.MID</code>).
* If a conflict is detected, the program will prompt you with options:
** '''Overwrite Duplicate Files'''
** '''Just Keep Incrementing'''
** '''Cancel the operation for that file'''

=== 4. View Results ===
* Once processing is complete, the program will display a log of the renamed files.
* You can now transfer the renamed files to a floppy disk or USB drive for use with your Disklavier.

== FAQ ==
=== Why do I need to shorten filenames? ===
Early Yamaha Disklaviers use a '''DOS-based file system''' that can only read filenames in the '''8.3 format'''. Longer filenames will not be recognized or played properly.

=== Does this change my original files? ===
No, the program '''creates a renamed copy''' and leaves your original files untouched.

=== What happens if I drop the same file twice? ===
If a file with the same name already exists, the program will either overwrite it or increment the filename, depending on your selected setting.
