How do I change the storage option on apps on my Samsung SJ5 to save to my SD card?

[AC Question]

The compulsory apps on my Samsung SJ5 use up almost all the 8GB...I have a 16GB SD card, but cant save files such as photos, recordings, emails to the SD card.

Some apps let you set the default save location to the SD card while some do not give you that option.
Check each app's settings.
For the apps that do not let you set the save location to the SD card, use your file browser app to copy the files to the card.
After you confirm that the files did successfully copy, you can use the file browser app to delete the old files from the internal storage.
