CHMOD files using FileZilla
This small tutorial will guide you through 'chmodding' a file using the latest FileZila FTP client (3.0.11.1) The process should be similar for all other FTP clients however.
If you haven't got FileZilla you can download it, for free, here:

Firstly an introduction. So what exactly is chmod and why do you have to do it? Well the chmod command is short for 'change mode' used in *nix platforms. It basically changes the modes of files and directories, such as their permissions. The reason why it is sometimes required to chmod files is because often we may want to write or execute a file on our server but we do not have the required permissions. Changing the file permissions using chmod will allow us to do this.
1. Open FZ and connect to your server
The first step is to open the FileZilla client and connect to your server.
2. Browse to the file you wish to CHMOD
Next you'll need to browse to the location of the file it is you wish to chmod. In this tutorial I will be altering the permissions on a txt file for a referral logger.

As you can see there is a permissions column which shows the current permissions for the files:

Where r = read, w = write and x = execute
3. Select the file attributes option
Right click the file you wish to edit, in my case it is refers.txt and select the
File Attributes... option.

This will bring up the the file attributes options menu with the current permissions shown:
4. Change the settings
Nearly there now! This bit is pretty simple: just change the values to suit your needs or what you have been instructed to do so. You can either type in the numeric value or simply check the correct permissions. Once you're done simply click OK. In this example I am changing the permissions to 777:
5. All done!
And that's it! Your client should have updated the permissions column to show your new permissions:
