SD Card not showing up but is installed

[Android Central Question]

Hi. So, I'm trying to move some pictures and music to my SD Card. But whener I try to do it, it doesn't show up in the file manager. If I connec the smartphone to my PC, the SD Card doesn't shot up either. But I can move full apps to the SD Card, just not files. What can I do?
