The Sony Xperia Live Walkman WT19i can be easily formatted but do not try to do it by yourself, always apply a how to guide that contains all the information needed. A how to format Sony WT19i can be found on the website, Android Geeks.
formats are 3GP, MP4, MP3, AAC, WMA. I found that off other site, hope it still helps!
