SyncBackPro/SyncBackSE incorrectly reports there are no files on the FTP server

In some rare cases, usually on old or very basic FTP servers, SyncBackPro/SE may incorrectly state that there are no files on the FTP server. When SyncBackPro/SE asks an FTP server for a list of files it asks for a list of all the files (included hidden files) and all the details about those files (e.g. size, last modification date and time, etc). However, when asked for a complete and detailed file list, some FTP servers incorrectly report that there are no files in a folder. To fix this you must modify your profile, switch to Expert mode, go to the FTP -> Advanced settings page, and enable the option Use LIST command without options.
