Error in continuously copying multiple files to USB drive

Hello, first of all, thank you very much for your open source framework.

I found some errors in copying multiple files. An error occurs when the number of consecutive copied files exceeds a certain number.

Not sure what you mean. This looks fine to me. No error?

Still how you managed to have every file name twice in the same folder is remarkable

When copying multiple files, the file name may be incorrect. Two files with the same name should not appear.
