Make sure to keep these instructions in mind:
- You may want to minimize the number of your .htacess files as too much configuration can slow your server down.
- Whenever your server detects a .htacess file in a directory, it will search for .htacess files in all the parent directories. This will expand your server resource usage.
- Higher .htacess files in the file path will take precedence.
Where Is htaccess File?
If you are wondering where does .htaccess file go, we should say that every server would have this file in the root folder. If you are not able to find it in the root folder, then it might be hidden. Enable the hidden file by going to the settings, and you will see a text file with the name .htaccess.
Generally, this file is saved in the root folder that holds all the files of your website. Go to the public_html or www folder, where you will find all the website template files. A single directory and multiple website subdirectories would have a separate .htaccess file in the root directories of each subdirectory.
Here are some tips on how to locate .htaccess file:
Why Can't I Find My .htaccess File?
On the webserver, the web files that begin with the dot (.) are hidden. You have to unhide the files by going to the settings. There are two ways you can unhide the hidden .htaccess files. Either you do this using the FTP login or go to the control panel, wherein the root directory will find the setting option to unhide the files.
The file manager in the control panel gives you the option “show hidden files,” which enables the user to unhide the file. The setting may differ based on the server; however, every server will allow you to unhide the hidden files. Usually, it is in the “Preferences” settings or “Folder Options.” In some servers, you will find it in the “View” menu.
What To Do if You Don’t Have an .htaccess File?
Once you have tried all above method to unhide the hidden file, if you still do not see .htaccess file in the root folder, then there are possibilities that your root folder do not have this file.
The first thing that you have to ensure is you have turned on “Show hidden files.” Often .htaccess files are created by default, and you will be able to access them when you enable the show hidden files setting.
Now, if you do not find the .htaccess location, then you have to create a new one.

There is another possible way where you can use contents that have been uploaded before by others, without needing to download the content and then upload it to your website, this whole operation is called hotlinking.
Note: important to mention that people whose contents have been hotlinked by other sites will endure an increase in server resource usage as the new site that is hotlinking the content will be using their server’s resources.
You can always avoid this by setting hotlink protection on your site. Read on to find about how to enable hotlink protection on your website.
- Firstly you have to sign in to your website through SFTP
- Download the .htaccess file from your /web/content folder.
- When you have got the .htaccess file on your computer you may add the following lines to the file:
- Make sure to put your actual domain instead of yourdomain.com also please do not modify any other codes within the .htaccess file.
- When you’ve finished adding the above lines, make sure to upload the .htaccess file back to your /web/content directory.
- Once you’re done with the uploading process, disconnect from SFTP and assess the website for any errors.
When Is It Better Not To Use .htaccess Files?
Generally speaking, using .htaccess files is the best option when you can’t gain access to the main server configuration file. There has been some misconception during the last decade such as user authentication and mod_rewrite directives always have to be done in .htaccess. while you can simply put user authentication configurations in the main server configuration and that is also the preferred way of doing the job.
.htccess can be used in cases where you need to make configuration changes to the server on a per-directory basis but you failed to gain root access over your server. Also in some cases, the server administrator wouldn’t grant permissions to make configuration changes, where it might be wise to permit some users to make these changes using .htaccess files for themselves.
Overall the use of .htaccess should be avoided whenever possible. Any configuration that you may desire to put in .htaccess files, can work just fine in the Directory section of a server.
