mod rewrite - Changing url path with .htaccess -

i'm trying rewrite

http://www.example.com/fr/index.html 

to hide in url folder fr

http://www.example.com/index.html 

the htaccess file in folder fr

this .htaccess file :

options -indexes rewriteengine on  rewritecond %{request_filename} !-d rewritecond %{request_filename}\.html -f rewriterule ^([^/]+)/$ $1.html  rewritecond %{the_request} ^[a-z]+\ /([^/]+/)*[^.]+\.html(\?[^\ ]*)?\ http/ rewriterule ^(([^/]+/)*[^.]+)\.html$ http://%{http_host}/fr/$1 [r=301,l]  rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewritecond %{request_uri} !(\.[a-za-z0-9]{1,5}|/)$   rewriterule (.*)$ http://%{http_host}/fr/$1/ [r=301,l] 

any appreciated. !

here new .htaccess but... nothing

rewritecond %{the_request} \ /fr/ rewriterule ^fr/(.*)$ /$1 [l,r=301]  rewritecond %{request_filename} !-d rewritecond %{request_filename}\.html -f rewriterule ^([^/]+)/$ $2.html  rewritecond %{the_request} ^[a-z]+\ /([^/]+/)*[^.]+\.html(\?[^\ ]*)?\ http/ rewriterule ^(([^/]+/)*[^.]+)\.html$ http://%{http_host}/$1/$2 [r=301,l]  rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewritecond %{request_uri} !(\.[a-za-z0-9]{1,5}|/)$  rewriterule (.*)$ http://%{http_host}/$1/$2/ [r=301,l] 

here solution. hope can :

options +followsymlinks rewriteengine on rewritebase /  # hide folder fr rewritecond %{request_filename}.html -f rewritecond %{request_uri} !/$ rewriterule (.*) $1\.html [l]  rewritecond %{the_request} ^[a-z]{3,}\s/+fr/([^\s]+) [nc] rewriterule ^ %1 [r=301,l]  rewritecond %{request_filename} !-f rewriterule (?!^fr/)^(.*)/$ /fr/$1 [l,nc] # end  rewritecond %{the_request} ^[a-z]+\ /([^/]+/)*[^.]+\.html(\?[^\ ]*)?\ http/ rewriterule ^(([^/]+/)*[^.]+)\.html$ http://%{http_host}/fr/$1 [r=301,l]  rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewritecond %{request_uri} !(\.[a-za-z0-9]{1,5}|/)$  rewriterule (.*)$ http://%{http_host}/fr/$1/ [r=301,l]
