Re: FTP clients
No it not worth buy FTP clients, you better off get free download manager that has build in FTP client like DAP, Gozilla, Reget etc. If you want to get rid of adverts then you will have to pay for it. I use DAP 8.1 Premium, it the best download manager and used the smallest memory footprint of 2 to 4Mb of memory than Free Download Manager used 8Mb of memory.
