Can't access System/download folder at Opencart - .htaccess

Question

I am using Opencart version 2.0.2.0. For My custom Module, I have used System/download folder for storing the uploaded images, and it was working fine. After renaming the .htaccess file, the page not found error occurs while accessing the System/download folder. I have searched lot for this issue, but i couldn't correct the issue
.htaccess:
# 1.To use URL Alias you need to be running apache with mod_rewrite enabled.
# 2. In your opencart directory rename htaccess.txt to .htaccess.
# For any support issues please visit: http://www.opencart.com
Options +FollowSymlinks
# Prevent Directoy listing
Options -Indexes
# Prevent Direct Access to files
<FilesMatch "(?i)((\.tpl|\.ini|\.log|(?<!robots)\.txt))">
Order deny,allow
Deny from all
</FilesMatch>
# SEO URL Settings
RewriteEngine On
# If your opencart installation does not run on the main web folder make sure you folder it does run in ie. / becomes /shop/

I have cleared the error by commenting the following line at .htaccess file,
RewriteRule ^system/download/(.*) /index.php?route=error/not_found [L]
.htaccess:
# 1.To use URL Alias you need to be running apache with mod_rewrite enabled.
# 2. In your opencart directory rename htaccess.txt to .htaccess.
