Description

The documentation for "File Filter Regex" property of ListSFTP processor reads:

Provides a Java Regular Expression for filtering Filenames; if a filter is supplied, only files whose names match that Regular Expression will be fetched

But it should be made clear that the Regex needs to match the whole filename. e.g. to filter files ending in ".txt.gz" the following will not work:

\.txt\.gz$

You'd need to specify:

.*\.txt\.gz

or equally:

.*\.txt\.gz$
