Ulefone Note 7P moving files

Hi all

I would like to know how to move files within the SD card.

I work for a company which sends me my payslips via email, I download them to my SD card but I want to move them to a folder for payslips (on SD card) but cant seem to figure out how, the way I'm doing it at the moment is to connect my fone to my laptop and move them that way. But I don't want to do that every time I want to move files.

Thanks in advance
