Error: EBUSY: resource busy or locked, rename

Hi,
I have a node red application

Node-RED version: v1.1.3
Node.js version: v12.18.3

move (fs-ops-move node) the file from folder_A to folder_B after 1 minute by setting the repetition in the inject node:

I put 27,000 files in folder_A, after the file move is completed, there are 4 files that cannot be moved to folder_B with the following error information:

Error: EBUSY: resource busy or locked, rename "Z:\data\folder_A\file_2943.zip" -> "Z:\data\folder_B\file_2943.zip"
Error: EBUSY: resource busy or locked, rename "Z:\data\folder_A\file_1546.zip" -> "Z:\data\folder_B\file_1546.zip"
Error: EBUSY: resource busy or locked, rename "Z:\data\folder_A\file_0220.zip" -> "Z:\data\folder_B\file_0220.zip"
Error: EBUSY: resource busy or locked, rename "Z:\data\folder_A\file_9036.zip" -> "Z:\data\folder_B\file_9036.zip"

I have searched google for this error and it seems to be due to one of the following reasons:
①Because the file is opening :arrow_right: Before executing the file is not open
②Because of virus software :arrow_right: I only use Windows Defender
③Because of npm's cache error :arrow_right: I'm not sure

Has anyone encountered this error? Can you tell me exactly what could be the cause?
Thank in advance!
