static URL Rewriting the subdir

i already shearch, and i never found this that i am asking, soo i want to know if it is even possible... or not ...

I am testing this in IPB.Board 3.4.5, with the app IP.Downloads.
I have this static url in my site that users can acess to download one file:

mysite.com/files/file/2-filename.txt
The original dynamic url is something like:

.../?app=downloads&showfile=2
The change of the url is made by that app (IP.Downloads)...
- i want to change it to url:
  
  mysite.com/text/2-filename.txt
so when the user insert in browser

1 mysite.com/text/2-filename.txt
- they see the file
2 mysite.com/files/file/2-filename.txt
- they are rewrite to mysite.com/text/2-filename.txt
  - and see the file.

How can i do that? change from ( /files/file/ ) to ( /text/ ) ... that can be made by .htaccess or i have to change the app files? or is impossible?

::UPDATE::

I have done it! without .htaccess , i change the core files that rewrite the url...

see the Answer below ...

Thanks for any help.

Solution

I made it by changing the core files ... it is more simple for me, so i use this way. thanks @ravi-thapliyal for trying to help making this by .htaccess, but i prefer this way ...

First open this file:

{forum-root}/admin/applications_addon/ips/downloads/extensions

Edit this code ['idmshowfile'] in the $_SEOTEMPLATES = array

This will tell the server that when the user go to (myserver.com/text/) they want to see the file...

'idmshowfile' => array(

   'app'          => 'downloads',

   'allowRedirect' => 1,

   'out'          => array( '/app=downloads(&amp;|&)showfile=(.+?)(&|$)/i', 'text/$2-#{__title__}/$3' ),

   'in'           => array( 

       'regex'        => "#/text/(\d+?)-#i",

       'matches'  => array( 

           array( 'app'       , 'downloads' ),

           array( 'showfile'  , '$1' ))

           ) 

   ),

And add this code to $_SEOTEMPLATES = array, in any position ...

this will tell to server that if the user go to (myserver.com/files/file/) they will be rewrite the url (myserver.com/text/) , and see the file.

'idmshowfile2' => array(

   'app'          => 'downloads',

   'allowRedirect' => 1,

   'out'          => array( '/app=downloads(&amp;|&)showfile=(.+?)(&|$)/i', 'text/$2-#{__title__}/$3' ),

   'in'           => array( 

       'regex'        => "#/files/file/(\d+?)-#i",

       'matches'  => array( 

           array( 'app'       , 'downloads' ),

           array( 'showfile'  , '$1' ))

           ) 

   ),

You can add as many rewrites as you want to the Forum, and create nice and friendly SEO URL.

Of course i know that this file can be overwrite in future updates of the app, soo i will make backup, and if possibel create an hook or app to make this (... if possibel).
