CI framework removes index.php problems and asks for doubts

The current project is placed under the root directory to build the. htaccess file
Rewriterule ^ (. *) $/index.php/$1 [L]
This path can be removed index.php
But I put it under the CI file in the Level 2 directory.
Rewriterule ^ (. *) $/index.php/$1 [L]
Switch
Rewriterule ^ (. *) $/ci/index.php/$1 [L]
But I can't find the file directory.
What's the solution?
