Environment: http://Backend.AI Web UI

Description:
When a new folder is created in the http://Backend.AI Web UI, the folder list is not immediately updated to reflect the new folder. Users need to navigate to a different tab and return, or wait for some time before the newly created folder appears in the list.

Steps to Reproduce:

1. Go to the file section in the http://Backend.AI Web UI.
2. Create a new folder.
3. Observe that the new folder does not appear in the folder list immediately.

Expected Behavior:
The folder list should be updated immediately after a new folder is created, without the need for the user to navigate away or wait.

Actual Behavior:
The newly created folder does not appear in the folder list immediately. Users need to navigate to a different tab and return, or wait for some time to see the new folder.

Possible Solution:
Implement an automatic refresh or update mechanism for the folder list after a new folder creation action is completed.
