Hello,
No, the folder is not always used - it's only used for cleanup purposes (including file/folder removal).

Another possible cause would be the
"Do not overwrite existing file" option.
If you somehow manage to reproduce this in a sample, please forward that to me so I can further investigate this on our end and possibly fix it.
Best regards,
Catalin
