Your FTP account has ownership of the files and folders on the server. You may occasionally build or use a script that wants to write in a folder. In that case you need to make the folder or file writeable in FTP for the web server. This can be done using the CHMOD command.
The way this command is entered varies per FTP client. You can set up the folder permissions for many graphic sector clients by going to properties.
To make files or folders writeable you require the following permissions:
- Folders: CHMOD 770
- Files: CHMOD 660
Even when you wish to delete files from the relevant folder with FTP, you are required to set up the relevant rights accordingly.
