Transfer internal photos to sd card

[patchdog]

I have a Huawei y 300 which is not listed in the device forum, however, I should like to know how to transfer photos and videos from the internal memory to the SD card, maybe most of the Huawei do a similar transfer method.
I tried to send pics on Whatsapp but the pics say (media not on SD card) and will not go.
I have looked for trying to transfer the contacts also but with no luck. Is there a way to be able to send the photos.

Use a file manager app (like ES File Explorer, MyFiles or Total Commander) or plug the phone into a PC, open Phone and Card (they're both on the device, which will show up where your hard drive(s) do(es)) and drag the files the same way you'd drag any file from one place to another.
