Use FTP File Name Extensions to define the list of file name extensions for which the FTP service will either allow or deny access. Configuring specific file name extensions allows Web server administrators to customize which file name extensions the FTP service will allow or deny, which you can use to tighten security on your server. For example, if you deny access to *.EXE and *.COM files, you can prevent Internet clients from uploading executable files to your Web server.

Note |
|
The Edit FTP Request Filtering Settings dialog box allows you to specify whether unlisted file name extensions are allowed. You can fine-tune the file access restrictions for your server by specifying that unlisted file name extensions are not allowed, and using the FTP File Name Extensions feature to manually specify the list of file name extensions that are allowed on your server. |
