Where are the setting files imported from, can you provide me with a path relative to the root (I mean, relative to where the main index.php file of Drupal is)?
By default they are imported from a directory and/or path with following schema:
sites/default/files/config_RANDOM-HASH/sync
I mean, the RANDOM-HASH part of above is replaced, and can be anything.
The configuration folder's path can be set in "sites/default/settings.php" file (without quotes, and relative to your index.php),
but in multi-site environments, you may need to change "default" to something else.
Said file may import other files, which set the path, instead of setting the path directly in settings.php.
However, setting the path should look like:
$config_directories = array();
$config_directories['sync'] = '../d8_config/sync';
Which is again relative to index.php file (from Drupal's root, goes one folder up, for security-reasons).
Can we change the import path?
Yes, change the path in the above said settings.php file.
Does cim command remove the files after they are imported?
No.
Can we tell drush to just delete any (previously exported) setting files?
Each time we export configurations, the old configuration files will be all deleted,
and new files get created based on database (where the old files were).
Note that drush cdel takes configuration object as input argument, and deletes it (from the active configuration) in the database, not the exported .yml files.
