[I] [Bug]: Minio Connection (VFS) can't list folders or bucket files inside a folder (hop)

steewel opened a new issue, #6608:
URL: https://github.com/apache/hop/issues/6608

   ### Apache Hop version?
   
   2.17
   
   ### Java version?
   
   jdk-17.0.12
   
   ### Operating system
   
   Windows
   
   ### What happened?
   
   Testing the new Minio VFS Connector I just confirmed that I can list files without having to know before hand each filename individually, but the VFS can't list files inside any folder or even list the folders inside the bucket.
   
   I uploaded this structure to my "hoptest" bucket to test it out
   ```
   C:.
   |   file_at_root_level01.txt
   |   file_at_root_level02.txt
   |   file_at_root_level03.txt
   |
   \---depth1
       |   file_at_depth1_level01.txt
       |   file_at_depth1_level02.txt
       |   file_at_depth1_level03.txt
       |
       \---depth2
               file_at_depth2_level01.txt
               file_at_depth2_level02.txt
               file_at_depth2_level03.txt
   ```
   
   The structure on minio's side:			
   ```
   mc ls miniolab/hoptest --recursive
   [2026-02-18 13:34:42 -03]     0B STANDARD depth1/depth2/file_at_depth2_level01.txt
   [2026-02-18 13:34:42 -03]     0B STANDARD depth1/depth2/file_at_depth2_level02.txt
   [2026-02-18 13:34:42 -03]     0B STANDARD depth1/depth2/file_at_depth2_level03.txt
   [2026-02-18 13:34:42 -03]     0B STANDARD depth1/file_at_depth1_level01.txt
   [2026-02-18 13:34:42 -03]     0B STANDARD depth1/file_at_depth1_level02.txt
   [2026-02-18 13:34:42 -03]     0B STANDARD depth1/file_at_depth1_level03.txt
   [2026-02-18 13:34:53 -03]     0B STANDARD file_at_root_level01.txt
   [2026-02-18 13:34:53 -03]     0B STANDARD file_at_root_level02.txt
   [2026-02-18 13:34:53 -03]     0B STANDARD file_at_root_level03.txt
   ```
   
   How my Minio Connection is set:

   The result when I try to list files inside folders:
   <img width="2019" height="558" alt="Image" src="https://github.com/user-attachments/assets/38f0b1bc-4381-462d-a94f-fa75958f7d1e" />
   If I try to list just the files inside the folder **depth1/depth2**:
   <img width="956" height="275" alt="Image" src="https://github.com/user-attachments/assets/b436aca8-7bf9-4ea4-b865-da329248cd5d" />
   
   
   The expected behavior would be list files and folders applying the "Include subfolders" when needed.

   I am unable to reproduce this, but I noticed Minio does not like empty files.
