The Music and Videos and pic das not work well on my MicroSD 1GB on my phone but some work and same sayes Unsupported file and it is mp3 Music.

I'm sorry to say, but it sounds like the MP3 files in question aren't supported by your phone, and not the Memory card. They may be corrupt files, or an unsupported version of the file.

Corrupt files can be checked by attempting to open them on another device or on your PC.

I wish it were easier to explain, but with MP3 files there are different Bit Rates - these are the speeds of how much music is there. The higher the bit rate the better the quality of the music. Some devices aren't compatible with really high bit rates. The lower the bit rate, the smaller the file size, but you lose quality with such files.
If you can play these files on your PC, I would check to see what the bit rate is on them. You may be able to see this by right clicking on the file and see the properties. You may have to view this from within your audio player - Windows Media Player or iTunes.
Compare this to a file that you know plays on your phone. See the difference? I believe this file will be at a lower bit rate.
I'm not sure how you would convert them to a lower rate. But if you've "ripped" them from a CD, then re-rip them and select a lower rate.

Also some phones or Music players (MP3 players) can only play MP3 files. It may be possible the file is an WMA file instead. This is another format altogether, and your computer may be able to play it, but your device might not.
There's a give and take with MP3 files as you can see.



I hope this is helpful.
