Is there a way to hide files that are being used by the library?

[DiegoEstradaS]

So i have a bunch of fonts, jpg files that i'm using to illustrate my GUI, wich is a Temperature Datalogger itself, so i was wondering how it could be possible to hide all of this files used by the library, (but leave them accesible for the library) except for those generated by the SD.h library(generally .txt files), so when i pullout the SD card only the .txt files are visible, that way it would be more difficult to delete these data files(fonts,jpg,etc)
