How to create and store files system (such as EFs, DFs) inside smart card?

[leonard]

I'm suppose to create 7 EF files with fake data is created by myself, and store these files inside smart card to select and read these files content then.
Have any possible ways to do that? please give some instruction or links of any tutorial.
Many thanks !
