Plugin Help Checking files in folder [FIGURED-OUT]

I have folder like this:

Code:

+plugins
+VoteShop
  -settings.yml
  -playerData.yml
  +shops
   -[1] Shop.yml
   -[2] Shop.yml

(+ = folders, - = files)

I want to count them, so I have this:

Code:java

    public int getNumShops(){
        int i = 0;
        YamlConfiguration test;
        test = fm.getConfig("shops" + File.separator + "[" + (i + 1) + "] Shop.yml");
        while((fm.getData(test, "shops" + File.separator + "[" + (i) + "] Shop.yml")) != null){
            test = fm.getConfig("shops" + File.separator + "[" + (i + 1) + "] Shop.yml");
            fm.setData(test, "settings.somethingVeryUseful", true, "[" + (i + 1) + "] Shop.yml");
            i++;
        }
        return i;
    }

FileManager (fm) class:

Code:java

public class FileManager {
 
    VoteShop plugin;
    String name = "VoteShop";
 
    public FileManager(VoteShop plugin) {
        this.plugin = plugin;
    }
 
    public YamlConfiguration getConfig(String name) {
        YamlConfiguration config = YamlConfiguration.loadConfiguration(new File(plugin.getDataFolder().getParentFile()+ File.separator+ this.name+ File.separator + name));
        try {
            config.save(plugin.getDataFolder().getParentFile() + File.separator+ this.name + File.separator + name);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return config;
    }
 
    public void setData(YamlConfiguration file, String path,Object value, String nameToSave) {
        file.set(path, value);
        try {
            file.save(plugin.getDataFolder().getParentFile()
                    + File.separator + name + File.separator + nameToSave);
        } catch (IOException e) {
            plugin.getLogger().info("Error saving yml file");
        }
    }
 
    public Object getData(YamlConfiguration file, String path) {
        return    file.get(path);
    }
}
 

(I removed few unuseful methods for making it shorter)

Problem is, even if I have like 5 [x] Shop.yml files, method(getShopsNum()) is still returning 0!!
Any solution? :/
P.S.:If I removed something useful, tell me, I'll add it.

New getNumShops() method, still ain't working

Code:

    public int getNumShops(){
        int i = 0;
        YamlConfiguration test = fm.getConfig("shops" + File.separator + "[" + (i + 1) + "] Shop.yml");
        fm.setData(test, "settings.somethingVeryUseful", true, "[1] Shop.yml");
        while(fm.getData(fm.getConfig("shops" + File.separator + "[" + (i + 1) + "] Shop.yml"), "settigs.name") != null){
            log("Log message in while loop in getNumShops(), while i = " + i + " : " + fm.getData(fm.getConfig("shops" + File.separator + "[" + (i + 1) + "] Shop.yml"), "settigs.name"));
            i++;
        }
        log("Log message in end of getNumShops(): " + fm.getData(fm.getConfig("shops" + File.separator + "[" + (i + 1) + "] Shop.yml"), "settigs.name"));
        log("i: " + i);
        return i;
    }

Well, at the ned, I did it like this:

Code:

    public int getNumFiles(){
        File folder = new File(plugin.getDataFolder() + File.separator + "shops");
        int i = 0;
        File[] files = folder.listFiles();
        i = files.length;
        log("Detected " + i + " shop(s).");
        return i;
    }

Thanks to nobody!
