# tSCPFileExists Verifies the existence of a file on the defined SCP server. tSCPFileExists checks, over a fully encrypted channel, if a file exists on a remote host. ## tSCPFileExists Standard properties These properties are used to configure tSCPFileExists running in the Standard Job framework. The Standard tSCPFileExists component belongs to the Internet family. The component in this framework is available in all Talend products. ## Basic settings | Properties | Description | | --- | --- | | Use an existing connection | Select this check box and in the Component
List drop-down list, select the desired connection component to
reuse the connection details you already defined.

Information noteNote: When a Job contains the parent Job and the child Job, do the following if you
want to share an existing connection between the parent Job and the child Job (for example,
to share the connection created by the parent Job with the child Job).

  1. In the parent level, register the database connection to be shared in the Basic settings view of the connection component which creates that very database connection.
  2. In the child level, use a dedicated connection component to read that registered database connection.


For an example about how to share a database connection across Job levels,
see [Sharing a database connection](https://help.qlik.com/talend/r/en-US/7.3/studio-user-guide/sharing-database-connection). | | Host | SCP IP address. | | Port | Listening port number of the SCP server. | | Username | SCP user name. | | Authentication method | SCP authentication method. | | Password | SCP password.
