Greeting dear M Comunnity.

I wanted to ask if there is faster way to check if a file contais anything else except "" just checking the file kb
I use this code for now: 

for (int x = 1; x < 32; x++)
            {
                for (int l = 1; l < 321; l++)
                {
                    string data = "";
                    if (x > 9) { data = $"{x}.01.2022"; }
                    if (x < 10) { data = $"0{x}.01.2022"; }

                    StorageFolder folderSP = await KnownFolders.DocumentsLibrary.GetFolderAsync("Św. Puszcza App");
                    try { StorageFolder folderDATA = await folderSP.GetFolderAsync(data); }
                    catch { Windows.Storage.StorageFolder folderDATA = await folderSP.CreateFolderAsync(data, CreationCollisionOption.ReplaceExisting); }
                    StorageFolder nowyfolderDATA = await folderSP.GetFolderAsync(data);
                    try { StorageFile plik = await nowyfolderDATA.GetFileAsync(l + ".dat"); }
                    catch { Windows.Storage.StorageFile plik = await nowyfolderDATA.CreateFileAsync(l + ".dat", CreationCollisionOption.ReplaceExisting); }
                    Windows.Storage.StorageFile plikPOKOJ = await nowyfolderDATA.GetFileAsync(l + ".dat");
                    string text = await Windows.Storage.FileIO.ReadTextAsync(plikPOKOJ);

                    pasek_ladowania.Value = pasek_ladowania.Value + 0.0493;
                    // 01
                    if (x == 1)
                    {
                        if ((l == 1) && (text == "")) { _2_os.Text = _2_os.Text + " " + l + ","; 
...
}

    @Nico Zhu (Shanghai Wicresoft Co,.Ltd.) 

    private async void check()  
{  
loading_bar.Value = 0;  
var tasks = new List<Task>();  
for (int days = 1; days < 32; days++)  
{  
tasks.Add(Task.Run(async () =>  
{  
await Task.Delay(TimeSpan.FromSeconds(0.01));  
for (int room = 1; room < 321; room++)  
{  
loading_bar.Value = loading_bar.Value + 0.0493;  
string date = "";  
if (x > 9) { date = $"{x}.01.2022"; }  
if (x < 10) { date = $"0{x}.01.2022"; }  
StorageFolder folderApp = await KnownFolders.DocumentsLibrary.GetFolderAsync("My Application");  
try { StorageFolder folderDATE = await folderApp.GetFolderAsync(data); }  
catch { Windows.Storage.StorageFolder folderDATE = await folderApp.CreateFolderAsync(data, CreationCollisionOption.ReplaceExisting); }  
StorageFolder newfolderDATE = await folderApp.GetFolderAsync(data);  
try { StorageFile file = await newfolderDATE.GetFileAsync(room + ".dat"); }  
catch { Windows.Storage.StorageFile file = await newfolderDATE.CreateFileAsync(room + ".dat", CreationCollisionOption.ReplaceExisting); }  
Windows.Storage.StorageFile fileROOM = await newfolderDATE.GetFileAsync(room + ".dat");  
string text = await Windows.Storage.FileIO.ReadTextAsync(fileROOM);  
if (days == 1)  
{  
if ((room == 1) && (text == "")) { room4two.Text = room4two.Text + " " + room + ","; }  
if ((room == 2) && (text == "")) { room4two.Text = room4two.Text + " " + room + ","; }  
etc...blah blah blah.,..  
}  
}  
}));  
}    
Task t = Task.WhenAll(tasks);  
loading_bar.Visibility = Visibility.Collapsed;  
}

    App is for calculating and showing available rooms from checking all room files from saved data.
    Problem: not calculating or not showing anything.
