ftpdmin

Ftpdmin is intended to be run temporarily, on an as-needed basis basis to do file transfers between Windows computers without going thru the trouble of trying to configure windows file sharing or an FTP server.
Also useful for Windows to Linux if the Linxu computer doesnt happen to have an FTP server already set up and configured.
Ftpdmin is not intended as an internet FTP server, or even intended to be left running.
Rather, Ftpdmin is started from the command line so that another computer can connect to it via FTP, typically over a LAN. When the file transfers are done, stop Ftpdmin. No installation is necessary to use it.
Ftpdmin has no notion of security or even passwords. Rather, once it is running, everyone can connect to it. The only resemblance of security is the -g option (get only, disallows put), and the ability to specify a directory that ftpdmin shall consider the root directory.

How to use ftpdmin

In order to use ftpdmin, you must have a LAN connection between the two computers. It should be possible to ping either computer from the other.
On one of your computers, run ftpdmin.exe. On starting, ftpdmin will display which address it is listening on. You can now FTP this computer from another computer.
You can use any FTP program you like, including the ones included with Windows. if you dont know how to use FTP, you can use explorer. Simply type the address that ftpdmin displays into your browser - such as "ftp://1.1.1.1".
When you are done transferring files, remember to stop ftpdmin.
