The FTPExtensionMap.txt file (Windows) and the FTPExtensionMapMac.txt file (Macintosh) map filename extensions to FTP transfer modes (ASCII or BINARY).

Each line in each of the two files includes a filename extension (such as GIF) and either the word ASCII or the word BINARY, to indicate which of the two FTP transfer modes should be used when transferring a file with that extension. On the Macintosh, each line also includes a creator code (such as DmWr) and a file type (such as TEXT). When you download a file with the given filename extension on the Macintosh, Dreamweaver assigns the specified creator and file type to the file.

If a file that you are transferring doesn’t have a filename extension, Dreamweaver uses the BINARY transfer mode.

Note:

Dreamweaver cannot transfer files in Macbinary mode. If you need to transfer files in Macbinary mode, you must use another FTP client.

The following example shows a line (from the Macintosh file) that indicates that files with the extension .html should be transferred in ASCII mode:

 HTML DmWr TEXT ASCII

In both the FTPExtensionMap.txt file and FTPExtensionMapMac.txt file (Macintosh), all elements on a given line are separated by tabs. The extension and the transfer mode are in uppercase letters.

To change a default setting, edit the file in a text editor.

Add information about a new filename extension

  1. Edit the extension-map file in a text editor.

  2. On a blank line, enter the filename extension (in uppercase letters) and press Tab.

  3. On the Macintosh, add the creator code, a tab, the file type, and another tab.

  4. Enter ASCII or BINARY to set an FTP transfer mode.

  5. Save the file.
