These changes are intended to improve interoperability with other systems:

  • support extended ASCII in file names
  • skip hidden/system entries (e.g. 'System Volume Information', '.DS_Store') during FS navigation

And for convenience:

  • detect file close from within ISR

Hey @mcaldwelva,
Something went wrong with the build.

TravisCI finished with status errored, which means the build failed because of something unrelated to the tests, such as a problem with a dependency or the build process itself.

@mcaldwelva please don't worry about that CI failure. It was already broken before this.

Thanks so much for your PR!
