LIBC have the opendir,,readtdir,closedir function that perform this
Code:

   1. #include <stdio.h>
   2. #include <sys/types.h>
   3. #include <dirent.h>
   4.
   5. int main()
   6. {
   7.     struct dirent *lecture;
   8.     DIR *rep;
   9.     rep = opendir("." );
  10.     while ((lecture = readdir(rep))) {
  11.         printf("%s\n", lecture->d_name);
  12.     }
  13.     closedir(rep);
  14. }

Put the result of the readdir in a table or a linked list
and implement a GU that display it after this uset for example the up & down key
to navigate and the button X to selection.
See below a sample that perform this.
Code:

#include "psp_pdf.h"

#define  DIRECTORY 1
#define  FILE      2

struct FILECHOOSER
{
   char name[32];
   char path[256];
   int type;
   struct FILECHOOSER *droite;
   struct FILECHOOSER *gauche;
} *tete = NULL;

void create_list(char *path)
{

   struct FILECHOOSER *p,*q;
   
   DIR * dir_p;
   struct dirent * dir_entry_p;

   dir_p = opendir( path );
   if (dir_p == NULL)
     {
       triLogError("opendir error\n");
       tete = NULL;
       return;
     }
   while( (dir_entry_p = readdir(dir_p)) != NULL)
   {
      if (strcmp(dir_entry_p->d_name,".") != 0)
        {
          p = (struct FILECHOOSER *) triMalloc(sizeof(struct FILECHOOSER));
          strcpy(p->name,dir_entry_p->d_name);
          strcpy(p->path,"path");
          if ( FIO_SO_ISDIR(dir_entry_p->d_stat.st_attr) )
                p->type = DIRECTORY;
          else  p->type = FILE;
          p->droite = NULL;
          q->gauche = NULL;
          if (tete == NULL)
               tete = p;
          else {
                 q->droite = p;
                 p->gauche = q;
               }
          q = p;
       }
   }
  closedir( dir_p );
}

void free_liste()
{

  struct FILECHOOSER *p,*q;
  p = tete;
  while (p != NULL)
  {
     q = p;
     p = p -> droite;
     free ( q );
  }
  tete = NULL;
}

void file_chooser(void)

  struct FILECHOOSER *q,*p;

     isrunning = 0;
     sceKernelExitGame();
   } 
   create_list("./");
   p = tete;
   sel = 0;
   while (isrunning)
   {
      q = p;   
      triClear( 0x000000 );
      i = 0;
      while( p != NULL  && i < 6)
      { 
         triFontActivate(impact16);
         if (i == sel)
                triFontPrint(impact16, 60.0f, 87.0f+i*32, WHITE,p->name); 
           else triFontPrint(impact16, 60.0f, 87.0f+i*32, BLUE,p->name);

         if (p->type == DIRECTORY)
           {
             if (strcmp(p->name,"..") == 0)
                  triDrawImage2(20.0f,75.0f+i*32,iback);
             else triDrawImage2(20.0f,75.0f+i*32,ifolder);
           }
         p = p -> droite;
         i++;
      }

      triSwapbuffers();
      triInputUpdate ();
 
      if (triInputHeld (PSP_CTRL_UP))
        if (sel > 0) sel--;
       
      if (triInputHeld (PSP_CTRL_DOWN))
        {
          sel++;
          if (sel > 5)
             {
                sel = 4;
                q = q->droite;
             }
       
        }
      if (triInputHeld (PSP_CTRL_CROSS))
        break;
      p = q;

Take this code that i've written for a packing tool , add the artistic part/event handling , also make the function "listFiles" recursive if you want , and you're ready to go...:

Code:

/*Listing.c (part of Packer.c)
   Author : 001xPOS
   Date    : Sep 07
*/

#include <stdio.h>
#include <dirent.h>

struct TEntry
{
    char* e_name;
    struct TEntry* next;
} TEntry;

struct TEntry *lastEntry = NULL, *entries = NULL;

void pushEntry(char* name)
{
    printf("Pushing entry %s \n",name);
    struct TEntry   * e = malloc(sizeof(TEntry));

    e->e_name = strdup(name);
    e->next   = NULL;

    if(lastEntry)
        lastEntry->next = e;
    else
        entries  = e;

    lastEntry = e;
}

void popEntries()
{
   while (entries)
   {
       printf("Removing entry %s \n",entries->e_name);
      lastEntry = entries->next;
      free(entries->e_name);
      free(entries);
      entries = lastEntry;
   }
}

void listFiles(const char* head_directory)
{
    printf("Building file list \n");
   struct dirent *dp = NULL;
   DIR*           dirp = opendir(head_directory);

    while ((dp=readdir(dirp)) != NULL)
    {
        if((!strcmp(dp->d_name,"."))||(!strcmp(dp->d_name,"..")))continue;
        pushEntry(dp->d_name);
    }
    closedir(dirp);
}

//lets test our list...
void iterateEntries()
{
    struct TEntry* e = entries;
   while (e)
   {
        printf("Iterating entry %s \n",e->e_name);
      e = e->next;
   }
}

int main()
{
    listFiles("..");
    iterateEntries();
    popEntries();
    return 0;
}
