Mapping is not dead yet

[SadNesS]

i know i'm annoying^^

i would have 2 questions:

#1
i have finished my first map i think, i have saved it in the default folder and can open it again. but when i look for the map on the pc it doesn't exist. neither in the gtk folder, nor in the et folder. where is the map? how can i test this?

#2
when i open my map in gtk again the textures suddenly disappeared. what did i do wrong?
