How to search directory and find folder's name in Azure filex

Hello every one

I am new to Azure RTOS, and now I want to search and find folders in USB or SDCARD but I could not find any function to do this. Is there any solution?

(working on STM32F)

something like this:

FRESULT scan_files (
    char* path        /* Start node to be scanned (***also used as work area***) */
)


  res = f_opendir(&dir, path);                       /* Open the directory */
    if (res == FR_OK) {
        for (;;) {
            res = f_readdir(&dir, &fno);                   /* Read a directory item */
						//sprintf(getfname, "%s", fno.fname);
					//len=strlen(getfname);
					//sprintf(getfname2[x], "%c",getfname[0]);
				
            if (res != FR_OK || fno.fname[0] == 0) break;  /* Break on error or end of dir */
            if (fno.fattrib & AM_DIR) {                    /* It is a directory */
                i = strlen(path);
              sprintf(path,"/%s", fno.fname);
						
                res = scan_files(path);                    /* Enter the directory */
                if (res != FR_OK) break;
                path[i] = 0;
            } else {                                       /* It is a file. */

    Hi @Ali Shahvaran Greetings. Welcome to Microsoft Q&A forum! Thank you for posting this question.

    I would like to check with you and see if you have looked into the GitHub repository on FlieX which provides an header file fx_directory.h which has different methods available to browse the directory.

    status = fx_directory_next_entry_find(&my_media, next_name);

    this function works but can't search inside a folder.
    How can set the address for this function or any alternative for that?

    Problem solved, this way:

    status = fx_directory_default_set(fx_media,"backgrand");
	status = fx_directory_next_entry_find(fx_media, next_name);

    just there is no way to set the default directory to the main path.
    why?

    Finally, I could find the solution this function works perfectly

    thank you so much 'Azure'

    UINT

    fx_directory_local_path_set

    (FX_MEDIA *media_ptr, FX_LOCAL_PATH *local_path_ptr,

    CHAR *new_path_name)

    ;
