filezilla is just a ftp client, your are not likely to recover that files unless you use any third party utilities, beware get an extra disc mounted to your server, and install recovery utilities on other disc, otherwise those utilities may acquire the space where your previous files were deleted, making a bigger panic.
Your host may have daily or weekly backups, you should try contacting them as VerdinaNET suggested. Also, in the future consider backing up your work using version control. The most popular cloud provider is GitHub: https://github.com/
