In my opinion, ftp manager is a program that allows you to manage files on the server using the ftp protocol. That is, write down, delete, set rights and edit. From all of the above, this program can only make directory listing, display information about files and edit text documents. So with the idea of downloading video directly from the server to the iphone, or, on the contrary, uploading your files to the network – break off. Manage files, set access parameters for them, there is no such possibility either. It is possible to edit ASCII documents, but here is an ambush, Cyrillic is not supported. It may be supported, but there is no way to change the encoding. The developers who created the FTP on The GO program probably know about this, but why they use the word ftp is not clear. The program, by the way, is paid. Instructions: how to install the program on an iphone via an .ipa file.
