The only path I see that is already present is the *std::filesystem::temp_directory_path*. The directories of interest (as I see) would be - *executable_directory_path*, *installed_directory_path* or maybe a better name, *bundle_directory_path*, directory where the executable is being run / has been installed. Assumed to be read-only. - *userdata_directory_path*, directory where current user stores data, "My Documents" on Windows for example. Assume permission required to write and read. - *cache_directory_path*, directory to data that persists longer than in *temp_diretory_path*, can be removed by OS if deemed necessary. "Library/Cache" on iOS for example. Assume write and read permission. - *appdata_directory_path*, directory where the application can store persistent data not to be shared with other application. "/data/data/" on Android for example. Assume write and read permissions. I'm sure there are plenty of other common useful paths you can think of in addition to the above. Is there anything like this already proposed and / or rejected?

Hello there,

I've been looking through the prop= osed C++17 Filesystem library and thought it would be a nice add-on to have= common paths. The only path I see that is already present is the std::f= ilesystem::temp_directory_path. The directories of interest (as I see) = would be
  • executable_directory_path, installed_director= y_path or maybe a better name, bundle_directory_path, directory = where the executable is being run / has been installed. Assumed to be read-= only.
  • userdata_directory_path, directory where current u= ser stores data, "My Documents" on Windows for example. Assume pe= rmission required to write and read.
  • cache_directory_path, directory to data that persists longer than in temp_diretory_path= , can be removed by OS if deemed necessary. "Library/Cache" on iO= S for example. Assume write and read permission.
  • appdata_dir= ectory_path, directory where the application can store persistent data = not to be shared with other application. "/data/data/<package_name&= gt;" on Android for example. Assume write and read permissions.
I'm sure there are plenty of other common useful paths you can t= hink of in addition to the above.

Is there anything like this alread= y proposed and / or rejected? If not, do you think this would be a good ext= ension to the Filesystem Library?
