28 * the value of `LV_FS_WIN32_LETTER` in `lv_conf.h`, and should not be
29 * confused with the Windows/DOS drive letter. It is an identifier that
30 * is used to enable LVGL to look up the appropriate driver from a list of
31 * registered file-system drivers. `lv_fs_win32_init()` happens to use the
32 * identifier letter 'C' so "C:" is the driver-identifier-prefix used here.
33 * The "C:" following that is indeed the Windows/DOS drive letter and is
34 * part of the actual path that gets passed to the OS-level functions.
35 *
36 * See https://docs.lvgl.io/master/details/main-components/fs.html for details.
37 * File Explorer uses `lv_fs` internally, thus the required prefix in path strings.
