Memory card full and will not open

You didn't specify the type of memory card so I'm assuming it's a Secure Digital card.

SD cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

hello try to format with active partition manager v3 (free )

What type and size memory card?

Does your SD card work in the other device you use? If so then it could be that the SD card isn't formatted correctly. I would try to hook up the device that works with the SD card.

Try to view the properties of your cellphone memory card, if its already full you really can't save anything there. The phone memory cant be fulled because it wont opened if its already full, but if the memory card isn't full perhaps your memory card is damaged.

1.for not reading the card its not comunicating with panel teminal propaly. Or its loose.
2.for the playlist slow,its wen the memory card is much or its all most full.

This kind of problem is mostly associated with cards that have been used previously or that have had some sort of formatting before.
The problem you are encountering is this, the card is full with system files that are mostly hidden. Majority of these files are usually log files that keep a record of all the activities the card might have undergone since it began usage.
The only thing you can do to solve this problem is to format the card suing your computer. Formatting the card would help you get rid of previously existing log files and would free up space for new pictures to be stored.
If this doesn't solve your problem, then you may be having a faulty card.
On the issue of having full internal memory, if you have the option to format your internal memory, go ahead.
If you don't change the default save location to the memory card if one is available.
Let me know if you need any assistance with formatting your card.

Sounds like you didn't format the cards in the camera first before using them. Try that now.

try to format memory card then used as usual.....

the wii will store gamesaves on itself, there is nothing to worry about, if you want to transfer or store certain game data, drag gamesaves to the SD card (wii memory card) using data management in the wii settings menu.
