The file system on the board is very tiny. (Smaller than an ancient floppy disk.) So, its likely you'll run out of space but don't panic! There are a couple ways to free up space.

One unique feature of Python is that the indentation of code matters. Usually the recommendation is to indent code with four spaces for every indent. In general, we recommend that too. '''However''', one trick to storing more human-readable code is to use a single tab character for indentation. This approach uses 1/4 of the space for indentation and can be significant when we're counting bytes.

However there are still some cases where hidden files will be created by Mac OSX.  In particular if you copy a file that was downloaded from the internet it will have special metadata that Mac OSX stores as a hidden file.  Luckily you can run a copy command from the terminal to copy files '''without''' this hidden metadata file.  See the steps below:

Once you've disabled and removed hidden files with the above commands on Mac OSX you need to be careful to copy files to the board with a special command that prevents future hidden files from being created.  Unfortunately you '''cannot''' use drag and drop copy in Finder because it will still create these hidden extended attribute files in some cases (for files downloaded from the internet, like Adafruit's modules).

To copy a file or folder use the '''-X''' option for the '''cp''' command in a terminal.  For example to copy a '''foo.mpy''' file to the board use a command like:
