SMB - Directories with additional attributes incorrectly detected as files

Current Situation

• If a file transfer uses an SMBFragment as the source with FileSpecSelection on a Directory, subdirectories with additional attributes (e.g. Hidden, Read-only, System) are incorrectly handled as files.
• This has the following consequences:
  1. The source file selection contains more entries than expected because these directories are incorrectly included as files.
  2. The transfer of these entries to the target fails because they are directories and not files.

Desired Behaviour

• Directories should be correctly identified as directories, regardless of additional file attributes such as Hidden, System or Read-only.
• Only actual files should be included as file entries in the source file selection.
• The file transfer should not fail because directories with additional attributes are incorrectly treated as files.

Test Instructions

• Create subdirectories with additional attributes (e.g. Hidden and Read-only) within the configured Directory.
• Start a file transfer using FileSpecSelection on the configured directory.
• Verify that the subdirectories are not included as file entries in the source file selection.
  • This information can be verified, for example, at DEBUG log level or by analyzing the entries during the transfer to the target.
• Verify that the file transfer completes successfully without attempting to transfer the subdirectories as files.
