I can not delete wrong files, they are prohibited

My site is zwac.000webhostapp.com
I’m trying out some actions regarding filetransfer. Result is 3 files that are wrong but I can not delete or rename them. The Filemanager sees them as directory’s and the php_rmdir function returns the message Prohibited directory name. Can someone else delete this files?

Hi!

We apologize for inconvenience, we’re aware the File Manager does not handle correctly some special characters in file/path names; fix is in progress and will be rolled out asap, until then we recommend to try using an FTP client such as FileZilla for such case.
