1) We have tested Auto FTP Manager on Pentium 4 with Hyper Threading, which simulates a dual processor. Therefore, Auto FTP Manager should not have a problem running on a Xeon processor.
2) You may use the Association List in order to specify the file type to use for a particular extension. Auto FTP Manager already specifies some default settings that should be sufficient.
3) This is possible if you correctly set the Action Rules (default settings should work). Synchronization will delete the remote file if a corresponding local file is not present and vice-versa.
