# Changing your file association preferences [edit]

This page describes how you can use Aptana, even if you are developing with ASP, PHP or other languages not yet supported by Aptana.

## Introduction

By default, you can use Aptana to create and edit JS, CSS, HTML, PHP, and XML files. However, you can use the various Aptana Editors with other file types, such as ASP files, by configuring support for those file types.

## Instructions

To configure alternate editor support for non-Aptana file types:

1. From the Window menu, select Preferences..., and then choose General > Editors > File Associations.
2. Add the appropriate file type.
   1. Next to the File Types list, click the Add button.
   2. In the New File Type pop-up window, type the appropriate file extension (e.g. "*.asp" or "*.php").
   3. Click OK to add the New File Type to the List.
3. Associate the new file type with Aptana.
   1. On the File Types list, select the file type that you just added.
   2. Next to the Editor Associations list, click the Add button.
   3. On the Editor Selection pop-up window, select the editor that you want to associate with your file type.
   4. Click OK to add the editor.

      The new is now associated with the specified file type.

4. Click OK to apply your changes and close the Preferences window.
