FX Directory navegation

Hi,

I am using FX on USBX Mass Storage Class.

Inside my memory stick I have several folders and files.

I need to search for a specific folder and enter it.

I am able to search for the folder using something like this:

/* First pass: only directories are added to the list */
while (1)
{

fx_directory_next_full_entry_find(g_fx_media_ptr, filename, &attributes, 0, 0, 0, 0, 0, 0, 0);

if (attributes & FX_DIRECTORY)
{

if(!strcmp(filename, desired_dir_name))

{

// Found

}
}

But how can I ENTER that folder once I have found it?

Best regards,
