y phone storage is full and I need to clear resources and don't know how to do this?

[AC Question]

I have an Alcatel A564C. I tried to message a video in a private message on facebook messenger, and it stopped and I got message that says " Attention: The phone storage is full, please clear some resources." I don't know how to fix this and it won't let me do anything but manage applications. I am not sure which applications I should disable or uninstall ?? Please help.

Delete some files or uninstall some apps. (Only uninstall apps you installed. Disabling apps doesn't free any space.)
