SD card Invalid file format message solution

I see the strange problem in my Micro SD memory Card, when I receive files from other mobile phones to my phones through bluetooth, When I play or run the recived file, it always say Invalid file or Invalid file format and received file name also changed into some special characters.
Aleady received file were running in my mobile without any problem.
One solution would have to format the SD card through my mobile, that could be the easiest and fast solution but I did not want to loss my files so, what I did, to solve this problem without lossing my data:

1. Take out the memory card from phone.
2. Put the card into SD card Reader, and insert into PC.
3. Just scan the memory card drive as we scan our hard drive partitions.

After scanning, the message appears that, your drive is scanned and some error were fixed then, I put the memory card into mobile phone. Not that every thing is working fine.
