I need to clear up my log files because at the moment my access log is ccess log is 421 mb.

From the picture below, could somebody tell me which files are safe to delete and which files to delete, I have little experience with log files so any help you could give me on the subject would be great.

If you've got shell access rather than delete them you can login via SSH (perhaps using PuTTY) and set the files to 0 bytes like this:

Once your logged in as admin or root copy and right click in this command:

echo -n > /path/to/log/httpd/log_file_name

check with your host if your uncertain about doing this
