Default FTP Directory Browse Settings <directoryBrowse>


The <directoryBrowse> element is used to specify the content settings for directory browsing on FTP sites. When you configure directory browsing options, all directories in an FTP site will use the same settings. The directory browsing settings will typically only affect command-line FTP clients, but may impact some graphical FTP clients. For example, a graphical FTP client might not work with the MS-DOS style of directory listings, in which case you would need to configure the UNIX directory listing style.


Version Notes
IIS 7.5 The <directoryBrowse> element of the <ftpServer> element ships as a feature of IIS 7.5.
IIS 7.0 The <directoryBrowse> element of the <ftpServer> element was introduced in FTP 7.0, which was a separate download for IIS 7.0.
IIS 6.0 N/A

Note: The FTP 7.0 and FTP 7.5 services shipped out-of-band for IIS 7.0, which required downloading and installing the modules from the following URL:

With Windows 7 and Windows Server 2008 R2, the FTP 7.5 service ships as a feature for IIS 7.5, so downloading the FTP service is no longer necessary.

Configuration Sample

The following configuration sample displays an example <siteDefaults> element for a server that is configured to display UNIX-style directory listings and the available drive space for directory listings.

      <directoryBrowse showFlags="StyleUnix, DisplayAvailableBytes" />

Sample Code

The following code samples configure the FTP site defaults to display UNIX-style directory listings and the available drive space for directory listings.


appcmd.exe set config -section:system.applicationHost/sites /siteDefaults.ftpServer.directoryBrowse.showFlags:"StyleUnix, DisplayAvailableBytes" /commit:apphost

Note: You must be sure to set the commit parameter to apphost when you use AppCmd.exe to configure these settings. This commits the configuration settings to the appropriate location section in the ApplicationHost.config file.
