A. vsftp是单线程还是多线程的
多线程的，单线程的应用性能太低了
B. 哪种ftp软件可以多线程上传
LeapFTP,CuteFTP,都可以的
还要看你上传的服务器有没有线程限制
C. ftp进行多线程下载的机制是什么
就是利用ftp下载器把一个文件分成多块来下载，
一般来说分得块越多，下载的速度越快。
D. ftp可否实现多线程上传
没有FTP软件可以满足你的要求。因为FTP协议里没有给你多线程上传的办法。
E. 如何设置多线程FTP下载
FlashfXP只能单线程下载，可以先用FlashfXP登录FTP站点，选中你要下载的文件，右击鼠标，在出现的菜单上选择：“复制URL(Ctrl+U)”，FlashfXP会提示：“是否复制用户名及密码？”，选择“是”，然后打开迅雷，点“新建（Ctrl+N）”下载任务，在出现的界面上边：“网址（URL）”里面（Ctrl+V）填上刚刚粘贴的信息，这样迅雷就可以从你的FTP站点多线程下载文件了，而且你可以同时下载不同的文件，也是多线程的。当然，万一你的FTP站点是限制单线程下载的话，为了充分利用带宽，就只好同时下载其他文件来提高效率。万一你的FTP站点是限制每个IP只能单线程下载一份文件，这个办法可能就无能为力了。希望能帮到你，呵呵~~
F. FTP服务器可以使用多线程吗
可以的，就好比可以同时使用多个匿名用户是一样的，只受你ftp最大连接数的限制，希望对你有帮助。
G. FTP线程在那里设置
一般根据你连接的服务器，服务器一般规定在多少K作用，允许几个线程，就算你设置后也没有用，如果你强制下载对方会封你的IP ，导致你下载有苦难
H. C++程序中如何实现ftp多线程下载
本人不才,下面这个是从网络上转来的.不知可有帮助.
这是codeproject的关于ftp的实现，你可以去down源代码
Introction
StuffFTP is a free for life FTP client. This FTP client will allow you to connect to FTP servers and upload and download files.
Motivation
Why did I create and continue to support StuffFTP? First it is a learning experience, and since I just got laid off from my company, I decided to use some of the tools they have provided, its legal as I technically bought them and they do not have other programmers following in my footstep nor do they plan on hiring any, to create something for the community. I also used another FTP program that was freeware for a while and then became pay to use software with little to no notice. That irked me and a friend suggested I create my own FTP client. So I am.
Progress
This is currently a work in progress and I would be the first to say there is a lot of work to do. Since I am laid off, I have lots of time on my hands. And this is an excellent chance for me to learn some of the concepts of C++ that I wanted to, but never had the chance while I was working. I was hoping to get a job in San Jose, CA, but decided to hold off and live on saving for a while.
Guarantee
I will support this program as best as I can. I have already setup a website and forum for it, here. I use the forum because I have trouble responding to email especially when I get a whole bunch of SPAM everyday. There is no adware or spyware in the program, and I guarantee that it will be free for the life of the program.
Some people have already asked why I don't open source the project. The main reason is I do not know if I can. StuffFTP uses some proprietary third party libraries. I do not know if I can post the source code or header files to those libraries. So everyone will have to wait until I can get rid of those libraries or hear back from the companies concerning my question about releasing header and associated help files.
Tools
* MS Windows XP Professional
* MS Visual Studio .NET C++/MFC
* Clickteam Install Maker
* Clickteam Patch Maker
* Betaone.net forum members
* CXListCtrl by Hans Dietrich
3rd Party Libraries
The application uses Catalyst Socket Tools Library Edition and Professional UI GUI library. So far the support has been fair with Prof-UI and outstanding with Catalyst. The Catalyst tool is for the actual FTP connection and, as the name suggests, Prof-UI is being used for the GUI.
Updates
You can find the latest updates here and you can also find my latest ramblings, blogs, and support here. This is where you can find out all the latest versions and information.
How to contribute
Money! Just kidding you can contribute by downloading, using, and giving feedback on the program. That way I can determine which path to take with the application and which features to prioritize or not. Graphics is also where I need lots of help. I am left brained and can not draw a good stick figure to save my life. If you can help with graphics or anything else, please let me know. Also talk to me, I am bored. I have no job at the moment so I can use the company.
Features
* Able to upload/download from server/computer
* Connect to FTP sites using login
* Connect using other ports besides 21
* Delete, rename, and CHMOD a file

I. java中用多线程可以提高 ftp批量上传的速度吗
在带宽足够的情况，多线程各上传同的文件，是可以的。。。。。。。
