# 3.3. Other features

## 3.3.1. Queueing

Queueing means that you can set maximum number of transfers that are running simultaneously. Caitoo tries to keep this number. Of course that you can at any time start the transfer by hand.

This does NOT mean that you cannot drag more files into Caitoo then this number !

Caitoo keeps record of all registered transfers and opens them when needed. Use queuing when you have bad connection to Internet or slow modem like me :-)

It is useful also when you do not want to take all network bandwidth you can, but rather download file after file.

## 3.3.2. Resuming

Caitoo supports resuming, which is a feature supported by most of ftp servers and is present in HTTP 1.1 protocol. If you download some big file and after 75% of download connection error occurs, you do not have to start all over again, but simply register this transfer again and it will continue in the place where it stopped ( Caitoo will append to an existing file and not overwrite it ).

However, this feature does not work for all ftp and http servers. Caitoo will check, whether server supports this feature, and will show this infomation in the listbox. Later, if you need to stop the transfer, you can easily decide, whether it is a good idea.

HTTP resuming is somewhat special. Please consider it to be experimental and don't rely on it too much.

## 3.3.3. Expert mode

Expert mode is recommended for experienced users. Generally, when expert mode is on, Caitoo will not ask user to confirm operations.

This applies to deleting of transfer, confirming paste operations and save locations.

If some error occurs while starting transfer or while transfering, Caitoo will not show you the error message, but it will set transfer for retry without asking. This is very useful, if you drag many files into Caitoo and leave to do some other work. Caitoo will download files and when it can't connect, it will continue without asking.

It could be useful to use expert mode together with auto-disconnect / auto-shutdown mode. Drag files into Caitoo, turn on the expert mode, turn on auto-disconnect / auto-shutdown mode and leave.
