You select preferences to control file transfer features that appear in the Files panel.
Specifies which site (remote or local) is always shown, and in which Files panel pane (left or right) the local and remote files appear.
By default, the local site always appears on the right. Whichever pane is not chosen (the left one by default) is the changeable pane: this pane can display the files in the other site (the remote site by default).
Displays a prompt for transferring dependent files (such as images, external style sheets, and other files referenced in the HTML file) that the browser loads when it loads the HTML file. By default, both Prompt on Get/Check Out and Prompt on Put/Check In are selected.
It’s usually a good idea to download dependent files when checking out a new file, but if the latest versions of the dependent files are already on the local disk, there’s no need to download them again. This is also true for uploading and checking in files: no need if up-to-date copies are already at the destination.
If you deselect these options, your dependent files are not transferred. Therefore, to force the Dependent Files dialog box to appear even when these options are deselected, hold down Alt (Windows) or Option (Macintosh) while choosing the Get, Put, Check In, or Check Out commands.
Determines whether the connection to the remote site is terminated after the specified number of minutes have passed with no activity.
FTP Time Out
Specifies the number of seconds in which Dreamweaver attempts to make a connection with the remote server.
If there is no response after the specified amount of time, Dreamweaver displays a warning dialog box alerting you to this fact.
FTP Transfer options
Determines whether Dreamweaver selects the default option, after a specified number of seconds, when a dialog box appears during a file transfer and there is no user response.
Specifies the address of the proxy server through which you connect to outside servers if you are behind a firewall.
If you are not behind a firewall, leave this space blank. If you are behind a firewall, select the Use Proxy option in the Site Definition dialog box (Servers > Edit Existing Server (pencil icon) > More Options).
Specifies the port in your proxy or firewall through which you pass to connect to the remote server. If you connect through a port other than 21 (the default for FTP), enter the number here.
Put Options: Save Files Before Putting
Indicates that unsaved files are saved automatically before being put onto the remote site.
Move Options: Prompt Before Moving Files on Server
Alerts you when you attempt to move files on the remote site.
Opens the Manage Sites dialog box, where you can edit an existing site or create a new one.
You can define whether the types of files that you transfer are transferred as ASCII (text) or binary, by customizing the FTPExtensionMap.txt file in the Dreamweaver/Configuration folder (on the Macintosh, FTPExtensionMapMac.txt). For more information see, Extending Dreamweaver.
