I am uploading new files from my PC to a server every day. I want to remove the older files from the server after uploading new files. Is it possible to do this automatically?

Auto FTP Manager can remove the files from the server if those files are not present on your PC. If you have already created the Automated Transfer profile then just right click on the profile name from 'Profile List' and select the 'Edit Profile' option. Then go to the 'Transfer Rules' tab. On transfer rules, under the 'Action Rules' select the fourth check box 'Delete files from {Server location} if not present in {PC folder}' Next, add a daily schedule using the 'Configure' button under the schedule section. When the schedule runs, the files which you have in the PC folder will be uploaded to the server and the files on the server which are not present in the PC folder will be removed.
