Support FTP Active Mode

MS FTP.exe does not support the passive mode.
Can i use FTP.exe in MS ALL Windows OS ?

I don't fully understand the question, sorry.

FTP Active mode is considered to be outdated, as it doesn't work with firewalls. It also prevents more than 1 simultaneous connection from the entire PC / ip address (Ok, this can be worked around with the PORT command). Back in 1985 nobody thought about that, but nowadays people simply use the FTP passive mode which doesn't have those downsides. Therefore, I consider implementing FTP Active mode to not be worth the time and effort. If it shall be true, that the windows ftp.exe doesn't support passive mode, you can simply use curl.exe, which is shipped with any modern Windows anyways. Curl is well tested with fineFTP Server and uses ftp passive mode by default.

I am curious though, why you are using ftp.exe: Did you just know know about the existence of curl, or are there specific reasons?

Any Windows OS with FTP.exe,it is very convenient.
You do NOT need to download any other FTP client firstly.

OS: Windows 7 X64
Test : FTP.exe

OK, I see. We are dealing with legacy Windows OS here. Neither Windows 7, nor Windows XP should be used anymore, as those are out of support and are most likely insecure by now. But you are right, back then Microsoft did not ship curl.exe with Windows by default. For any modern Windows (Win10 and up), curl is present.

I changed the title of this issue to "Support FTP Active Mode". I personally currently don't have a justification to spend time on it, but let's see if there is more interest in this topic and if maybe anybody from the community is willing to make a PR for this.
