# NATIVE > [HTML Version](nativedirswitch.htm) This switch, /NATIVE\{:len\}, displays files in the native format of the host operating system. The _len_ specification (default 32) determines the maximum display width for the filespecs. If the filename exceeds that, it is terminated with ">" just as when /NATIVE is not used. /NATIVE causes the following other effects: · "Incompatible files" are treated like any other files (i.e. displayed instead of skipped). · File sizes are shown in bytes instead of blocks · File names are shown in upper and lower case as they really are. · When combined with /D, displays entire path for each file. Otherwise, displays just the filename + extension(s) (but for each new directory, displays the directory in native format instead of the DEV:\[p,pn\] format.) · /W will default to /W:2
