Description

The ListFile processor retrieves many times file information like the length, the lastModifiedTime, the isDirectory attribute. If the filesystem is remote, each of these method calls is blocking and involving a communication with the remote system.

We should avoid to retrieve the info more than once in order to improve performances.
