No space for models on F12E?

After some struggle i managed to install Devation on my Devo F12E. After that i tried to load a model to the TX. But if i connect it to the Computer it shows me only one file (tx.ini - 64kb), if i try to move a model.ini to the transmitter i get the error message: not enough space (model.ini is 4kb).
What did i do wrong? It shows up as a FAT formatted drive on my Win10, 64bit Computer..

Thank you in advance

This may clear things up for you, the F12E uses a compressed file structure due to the smaller storage chip of this transmitter.
