> I'm receiving an error from the FTP Component when its processing files in Camel 2.19.0.
> I'm trying to retrieve files using the Camel FTP component (Camel 2.19.0):
> from("ftp://my.host.com:21/my/relative/directory?download=true&stepwise=false&delete=false")
> {code:java}
> org.apache.camel.component.file.GenericFileOperationFailedException: Cannot retrieve file: RemoteFile[my/relative/directory/file1.txt] from: ftp://my.host.com:21/my/relative/directory?delete=false&download=true&stepwise=false

> I debugged the Camel FTP consumer and it looks like
> [on line 238 is where the relative path is getting prepended to the absolute path|https://github.com/apache/camel/blob/camel-2.19.x/components/camel-ftp/src/main/java/org/apache/camel/component/file/remote/FtpConsumer.java#L238]
> Interestingly enough, [the SFTP component is doing the same thing|https://github.com/apache/camel/blob/camel-2.19.x/components/camel-ftp/src/main/java/org/apache/camel/component/file/remote/SftpConsumer.java#L208] however it is working because 
> {code:java}
> RemoteFileOperations<ChannelSftp.LsEntry>
> {code}
>  does not set filename as an absolute path but 
> {code:java}
> RemoteFileOperations<FTPFile>
> {code}
>  does.
> Does anyone have any suggestions to work around this to get the FTP Conponent to consume the files? or am I doing something incorrectly?
> I'm using Camel 2.19.0
