Adding Custom File Extensions in Photo Supreme

1. Adding Custom File Extensions:

   • Go to Preferences: Open Photo Supreme and navigate to the Preferences menu.

   • File Handling Section: Locate the section labeled File Handling.

   • Other File Extensions: Within the File Handling section, you will find an option called Other File Extensions.

   • Add Extensions: Here, you can manually add any custom file extensions that are not natively supported by Photo Supreme. For instance, you could add proprietary formats or less common file types used in specific workflows.
      

2. Managing Files with Custom Extensions:

   • Once these extensions are added, Photo Supreme can manage these files within its catalog. This includes organizing, searching, and assigning metadata to these files just like it does with its natively supported formats.

   • Files with these custom extensions can be tagged, categorized, and included in collections, which helps in maintaining a centralized organization system for various file types.
      

3. Thumbnail and Preview Generation:

   • Relying on the Operating System: For these custom file extensions, Photo Supreme relies on the operating system (OS) to generate thumbnails and previews. This means that if the OS can generate a thumbnail or preview, Photo Supreme will display it within the interface. If the OS does not support thumbnail or preview generation for a particular file type, Photo Supreme may display a generic icon instead.

   • Using External Applications: If necessary, you can configure the system to use specific applications to handle these file types, which may enhance the ability of the OS to generate previews.
