--reduce_paths, --no_reduce_paths

9.58 --reduce_paths, --no_reduce_paths

Enables or disables the elimination of redundant path name information in file paths.

Windows systems impose a 260 character limit on file paths. Where relative pathnames exist whose absolute names expand to longer than 260 characters, you can use the --reduce_paths option to reduce absolute pathname length by matching up directories with corresponding instances of .. and eliminating the directory/.. sequences in pairs.
--no_reduce_paths is the default.


ARM recommends that you avoid using long and deeply nested file paths, in preference to minimizing path lengths using the --reduce_paths option.


This option is valid for 32-bit Windows systems only.
