Delete or rename folders

[Android Central Question]

I have a lot of folders from previous jobs that I need to have deleted and some names changed. I know how to do this on a computer but not on my phone. I don't have access to a computer. I have a Samsung j3 emerge. Please help

Welcome to Android Central! What kind of folders are you talking about? Directories on the phone's internal storage or SD card? Gmail labels/folders? Google Drive folders?
