Format is not supported.

If the music in the card can be played, others can't be played, maybe your mobile phone doesn't support this format.

Be infected by a virus

If you are infected with the virus, you can go to the next U disk killing tool on the Internet to repair it. In the computer's Tools-Folder Options-View options, you can see your own files by removing the check in front of "Hide protected operating system files (recommended)".

The memory card is not clean.

There are two ways, one is to use the cell phone grid, so the grid is not clean, and the other is to use the card reader to directly grid the memory card, so that the memory card will have nothing! But remember to back up the useful things in the memory card! Then search the related websites for backup of N73 original card, and put it into the memory card after downloading!

Exe file association is corrupted.

Exe is an executable file, but it cannot be run. Maybe this program is broken, or your exe file association is destroyed by a virus and needs to be repaired. Find a software that can repair the relationship between exe files and change its exe to cmd. Of course, you can also change exe to cmd for temporary use.

Incompatible memory card

The mobile phone is not compatible with this 2G card. Please change a 1G card.
