Problems with SD card - who really knows?

I always thought the data is on the SD card in the phone, but I can't pull data from SD on my phone via the APP: albums or music, because it works so only wirelessly and on the laptop it shows the data only partially on the SD… But even if I want to pull music on the laptop from SD to mobile phone or something else that does not work - why not, do I need a new music app or new albums app? Just want to hear music again, that my voice messages are gone, so I've resigned myself, but music would be great and photos too… Can someone please give me exact instructions, what can I do?

Is the SD card secured, the small sliding bar. Drag and Drop can do it easily. You can see it in the small probably only in the adapter.

And in the mobile phone must be set, which data is stored on the SIM or SD card.

This is in the BD.

Ok, I do not quite understand that yet, which sliding bar and which adapter? What should be drag and drop, and unfortunately I have no manual, have an SD of San Disk. Sry understand the technology is not quite

I took a couple of pictures and I answer you anew.

On each SD card is a very small slide on the side. If this is wrong, the card is blocked. Here only helps find good looking Try out.

On the adapter in the photo, lock stands. My in the SD card with which I'm just photographing is yellow. A backup against accidental deletion. So access lock.

Standard SD cards have the size of the adapter. What brand SD card you have is, it does not matter anyway. After all, each must fit with adapter or without in cellphone and Fotoapperate. Therefore, there's the adapter to push the small (still new SD card in the bottom of the adapter.

Drag and drop is the easy way to move files. The short and common name against Das hier,

Hold the mouse pointer until it is blue. Press and hold the mouse and move to where it should go. Do you know 100%

Is the same as Str + X and Ctrl V or cut and paste

And BD loads you off the net! You can't always search on paper.
