I'm working on a project and I'm also wondering how to extract the names of files in folders 

e.g. I'm in "CatA" catalog with 2 subfolders:

* "CatAA" with catalog "ExpAA" - aaa.zip inside
* "CatBB" with catalog "ExpBB" - bbb.zip inside

My goal is to list (get the file names) aaa.zip and bbb.zip file while being in a main "CatA" file.

```
string[] dirs = Directory.GetDirectories(@"C:\CatA");

        //checkedListBox1.Items.Insert(0, dirs.Length);

        for (int i = 0; i < dirs.Length - 1; i++)
        {
          //c# go a folder up
          dirs.
          var zipFiles = Directory.GetFiles(@"C:\Users\DLXP3B3\Desktop\tes", "*.zip");
          checkedListBox1.Items.Insert(i, zipFiles[i]);
        }

```

I have some work done, but I don't know how to proceed. Any ideas would be appreciated. Thank you.
