Files and folders that exist on a server have a "permissions" attribute that determines whether they can be read and modified. By default, when files and folders are uploaded, they are read-only and cannot be written to by an outside script or program.

Some web programs require files and folders be made writable through CHMOD. For instance, the WordPress program requires that the /wp-content folder be changed to writable so that files can be uploaded through the web interface. WordPress also requires the template sheets to be made writable to be editable through the web interface. CHMOD can be performed through your FTP client according to the following steps.

Step 1: Open your FTP client and find go to the folder or file you want to modify
You must be connected to your FTP client in order to perform this step. If you do not know how to install and use FTP, please read the corresponding tutorial:

After connecting to your FTP account, click your way to the file or folder that you need to modify. When you can see the file or folder in the server window, right click on the file or folder and click on "File Attributes"



Step 2: Perform the CHMOD
In the corresponding popup window, there will be some 3 number value such as "644." To make the file writable, just change that number to "777" and click OK. That is it, you are done!
