Este ma napadlo - ja by som este teoreticky dokazal prezit, ze sa mi .txt
nacitava do stringu, ale problem bude u velkych suborov, pretoze moj pokus s
2x800MB ascii subormi "foo.txt" a jeho kopiu "foo.bin" dopadol tak, ze
volanie attachFile() (a alternativa s DataSource) pre "foo.bin" trva zlomok
sekundy (vytvori sa len referencia na subor), ale u "foo.txt" to vyzere pamat
a crashne (nacitava 800MB do stringu).
