First off: Spell better.
Secondly: Use correct grammar.
Thirdly: Give more information on what you want.
Fourthly: Doubtful that many people are going to have much idea of what you're talking about.

Do you want to increase the storage capacity of the MP3 player in terms of gigabytes? I doubt that that is possible seeing as the hard drive of the MP3 is static, meaning unchangeable. There's no way to download a program or software that will increase the amount of memory your MP3 player can hold.
There may be, however, a program that will allow you to compress the MP3 files to save room. This does make your music or video files lower quality, but it saves space.

the program you need is MP3gain it can be downloaded from http://mp3gain.sourceforge.net/
the Moran that didn't answer your question because he was too high on himself was obviously caffeine tripping at the time.
