fix #1671

[cr-gpt]

Based on the code patch you provided, here's a brief code review:

1. Line 133: The change result.emplace_back(de.path().filename()); suggests that instead of adding the complete path to the result vector, only the filename is now being added. This change may be intentional if you only want to store the filenames in the vector. However, if you require the complete paths, you should revert this change.

2. Error Handling: The current code does not handle any exceptions or errors related to directory operations. It would be beneficial to add appropriate error handling, such as catching exceptions or checking for errors during directory iteration, and handling them accordingly.

3. Commenting: Consider adding comments or function documentation to explain the purpose and expected behavior of the functions CreatePath() and GetChildren(). This can make the code more understandable for future maintenance or collaboration.

4. Code Formatting: Make sure that the code adheres to consistent formatting standards throughout for better readability. For example, ensure consistent indentation and style conventions (e.g., using braces even for single-line statements).

5. Testing: It's essential to thoroughly test the modified code snippet to ensure that the changes work as intended and do not introduce any new bugs. Verify the functionality by running different scenarios and edge cases.

Overall, the changes seem relatively minor, but it's important to carefully evaluate the impact of modifying the original behavior and thoroughly test the code to ensure its correctness.
