hello? I am Park.
The error appears if I create a file with the same name in the same folder.
I can't create duplicate files so I can keep unique filenames.
I created a subfolder within the folder because the number of files increased.
The files I created are in a subfolder and not within the same folder.
If I create a file with the same name, no error appears.
When I create the same file name in a subfolder based on one parent folder,
Can you tell me how I can get the error to appear?
