cFile

Provides access to file systems, allowing files to be processed by any other
components or messages from other components to be saved to the disk.

cFile Standard properties

These properties are used to configure cFile running in the Standard Job framework.

The Standard
cFile component belongs to the Connectivity/File family.

Basic settings

Path	Path to the file or files to be accessed or saved.
Parameters/Noop	Select this check box to keep the file or files in the original folder after being read.
Parameters/Flatten	Select this check box to flatten the file name path to strip any leading paths. This allows you to consume recursively into sub-directories, but when you, for example, write the files to another directory, they will be written in a single directory.
Parameters/AutoCreate	Select this check box to create the directory specified in the Path field automatically if it does not exist.
Parameters/BufferSize(kb)	Write buffer sized in bytes.
Encoding	Specify the encoding of the file, ISO-8859-15, UTF-8, or CUSTOM.
FileName	The name of the file to be processed. Use this option if you want to consume only a single file in the specified directory.

Advanced settings

Advanced	Set the optional arguments in the corresponding table. Click [+] as many times as required to add arguments to the table. Then click the corresponding Value field and enter a value. See the site http://camel.apache.org/file2.html for available URI options.

Usage

Usage rule	cFile can be a start, middle or end component in a Route.
Limitation	n/a

Scenario: Reading files from one directory and writing them to another

This scenario applies only to a Talend solution with ESB.

In this scenario, an input cFile component is
configured to visit a local file directory and send the files in the directory to an
output cFile component which writes the files in
another directory.

Dropping and linking the components

From the Palette, expand the Connectivity/File folder and select the cFile component. Drop one as the input component
and another as the output component onto the design workspace.
Right-click the input cFile component,
select Row > Route in the contextual menu and click the output cFile component.
Label the components to better identify their respective
functionality.

Configuring the components

Double-click the input cFile component to
display its Basic settings view in the
Component tab.
In the Path field, browse to or enter the
input file path, and leave the other parameters as they are.
Double-click the output cFile component to display its Basic
settings view in the Component
tab.
In the Path field, browse to or enter the output file
path, as shown above. Leave the other parameters as they are.
Press Ctrl+S to save your route.

Viewing code and executing the Route

Click the Code tab at the
bottom of the design workspace to have a look at the generated code.

As shown in the code, a message route is built from one endpoint .to
another.
Click the Run view to display it and
click the Run button to launch the
execution of your Route. You can also press F6 to execute it.

RESULT: The input files are written to specified output directory.
