好的 FTP 源代码，将支持 FTP/SFTP

lftp服务器源码，相当地精简的一个ftp实现。(lftp server source code, a considerable downsizing of an ftp achieve.)

FileZilla is a powerful FTP-client for Windows 9x, ME, NT4, 2000 and XP. It has been designed for ease of use and with support for as many features as possible, while still being fast and reliable. (See FileZilla history for more information)

最新客户端自动升级程序 增强一些功能： 不重复下载， 上传时自动填写版本号。 softup.pbl ――上传文件 softupgrade.pbl ――下载文件 表结构： create table softupgrade( filever varchar(20), filename varchar(20), filedata long raw, primary key(filever ,filename )) -breaks automatic update features several enhancements : not to repeat the download and upload automatically complete version. Softup.pbl-- Upload file softupgrade.pbl-- download Table Structure : create table softupgrade (filever varchar (20), the filename varchar (20), filedata long raw, primary key (filever, filename
