Hello,

As described in the official doc - File picker - .NET MAUI | Microsoft Learn

Default file types are provided with FilePickerFileType.Images, FilePickerFileType.Png, and FilePickerFilerType.Videos. You can specify custom file types per platform, by creating an instance of the FilePickerFileType class

And you can refer to the following code:

async void DoPickCustomType()
{
     var customFileType =
         new FilePickerFileType(new Dictionary<DevicePlatform, IEnumerable<string>>
         {
             { DevicePlatform.iOS, new[] { "public.xml" } }, 
             { DevicePlatform.Android, new[] { "application/xml" } },//xml type
{ DevicePlatform.WinUI, new[] { ".xml" } }
         });
 
     var options = new PickOptions
     {
         PickerTitle = "Please select a xml file",
         FileTypes = customFileType,
     };
     var result = await FilePicker.Default.PickAsync(options);
     ...
}
