Hi
You can use the move option on the Camel file consumer, and then use a
bean to calculate the file name.
http://camel.apache.org/file2
move=bean:myFileCalculatorBean
<bean id="myFileCalculatorBean" class=...
And in the bean has a single method
public String calculateFileName(@Header(Exchange.FILE_NAME) String
existingName) {
// check if the file exists, and if so, then do your - number trick
to find a "free" name
...
}
