File Transfer Notes

FileZilla uses multiple FTP sessions. One session gets used purely to browse the server. The other sessions get used to do the file transfers. That way, you can always browse the server even during transfers.

For example, here is a simple car analogy: You order a pizza using your telephone (aka the browsing connection), then you hang up the telephone. Then the delivery man drives the pizza in his car to your location (the transfer connection). While the pizza is transferring, you can phone somebody else, like for example your garage because your own car is broken ;)

Reducing simultaneous connections for incorrectly configured servers

If you get a 421 Too many connections from this IP (<number>) error, the FTP server is restricting your number of connections. There are even servers restricting it to one connection at a time.

The preferred solution would be to contact the server administrator and encourage him/her to configure the server correctly (FTP uses more than one connection by design!). But if you need access immediately, there is a workaround:

1. Open the Site Manager (File - Site Manager... or the first toolbar button)

2. Create an entry for that server, enter all details you know, the more precise, the better

3. Open the 'Transfer Settings' tab

4. Tick the 'Limit number of simultaneous connections' checkbox

5. Enter the desired limit into the 'Maximum number of connections' field


Now, if you connect using the Site Manager entry, connections will be limited.

Note: If you limit connections to 1 only, there is a major drawback: You cannot browse the server anymore while a transfer is in progress!

Troubleshooting

Re-registering the shell extension (Windows only)

Especially on Vista it can happen that Drag&Drop fails and you get an error message stating the shell extension doesn't work. In this case you may need to re-register it. Here's how:


1. Open a command prompt as administrator. This is important!

Start Menu - All Programs - Accessories: Right Click 'Command Prompt', select 'Run as administrator'


2. Navigate to the Filezilla program directory. Example:

cd "\Program Files\Filezilla FTP Client"


3. Re-register the shell extension.

Type 'regsvr32 fzshellext.dll' (without quotes of course)


4. If you have 64bit OS, you need to perform an additional step.

Type 'regsvr32 fzshellext_64.dll' (no quotes as well)


If you get the reply 'DllRegisterServer in ... succeeded.', you've done it (though you probably still need to reboot your computer).
