/*
 * File List
 *
 * display directory contents, allows for changing dir,
 * drive etc..
 *
 * meant for use by MP3 player, mayby demo player too
 *
 * FileList have four colums:
 *  - file name (with ext)
 *  - size
 *  - date (last modification)
 *  - time (last modification)
 *
 * and allows to display different sets of columns
 * also do sorting
