Overview

The <fileHandling> element is used to specify the way that the FTP service handles file operations. For example, the keepPartialUploads attribute configures whether the FTP service should keep files that were partially transferred, such as when a file transfer ends prematurely.

Compatibility

Version	Notes
IIS x.0	The <fileHandling> chemical element was not modified in IIS 10.0.
IIS 8.5	The <fileHandling> element was not modified in IIS 8.5.

IIS 7.5	The <fileHandling> element of the <ftpServer> element ships equally a feature of IIS 7.5.
IIS 7.0	The <fileHandling> element of the <ftpServer> chemical element was introduced in FTP seven.0, which was a divide download for IIS 7.0.
IIS 6.0	N/A

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

Configuration

The <fileHandling> element is configured at the site level.

Attributes

Attribute	Clarification
allowReadUploadsInProgress	Optional Boolean aspect. truthful if the FTP service should allow read access to files that are currently beingness uploaded; otherwise, false. The default value is false.
allowReplaceOnRename	Optional Boolean attribute. true if the FTP service should allow files that are being renamed to overwrite existing files; otherwise, fake. The default value is fake.
keepPartialUploads	Optional Boolean aspect. truthful if the FTP service should keep files that take been partially uploaded; otherwise, false. The default value is false.

Child Elements

None.

Configuration Sample

The following sample displays a <fileHandling> chemical element for an FTP site that configures the FTP service to proceed partial uploads, to let replacing existing files when renaming files, and to deny reading files that are currently being uploaded.

              <site name="ftp.instance.com" id="5">   <application path="/">     <virtualDirectory path="/" physicalPath="c:\inetpub\www.example.com" />   </application>   <bindings>     <binding protocol="ftp" bindingInformation="*:21:" />   </bindings>   <ftpServer>     <fileHandling keepPartialUploads="true"       allowReplaceOnRename="truthful"       allowReadUploadsInProgress="false" />     <security>       <authentication>         <basicAuthentication enabled="true" />         <anonymousAuthentication enabled="false" />       </authentication>     </security>   </ftpServer> </site>                          

Sample Code

The following examples configure an FTP site then that it keeps partial uploads, allows replacing existing files when renaming files, and denies reading files that are currently existence uploaded.

AppCmd.exe

              appcmd.exe set up config -section:arrangement.applicationHost/sites /[name='ftp.instance.com'].ftpServer.fileHandling.keepPartialUploads:"True" /commit:apphost  appcmd.exe set config -section:organisation.applicationHost/sites /[proper name='ftp.example.com'].ftpServer.fileHandling.allowReplaceOnRename:"Truthful" /commit:apphost  appcmd.exe set config -section:organization.applicationHost/sites /[proper noun='ftp.example.com'].ftpServer.fileHandling.allowReadUploadsInProgress:"Fake" /commit:apphost                          

Notation

You must be certain to set the commit parameter to apphost when you employ AppCmd.exe to configure these settings. This commits the configuration settings to the appropriate location department in the ApplicationHost.config file.
