## **Auto Rename Midi Files .bytes**

**If this option is enabled, MIDI files with the extention .mid or .midi are automatically renamed with .bytes upon asset import, using an AssetPostprocessor. This simplifies the setup so that you do not have to manually change the file extension. However, if you do not wish for this to happen automatically, you may disable the setting in the preferences.&#x20;*****(Added in Timeflow v1.0.2)***

{% hint style="warning" %}
The [MidiFile ](/timeflow/reference/behaviors/midi.md#midi-file-load-tracks-and-notes-from-a-midi-asset-file)component requires all MIDI files to have the .bytes extension to properly import the binary data from a TextAsset. If the file otherwise has the .mid or other extension, it will not be recognized and will generate errors when attempting to parse the MIDI data.  &#x20;
{% endhint %}
