I'm trying to use the CREATEFILTER directive to: . Include all files WITHOUT an extension . Exclude all files WITH an extension . Exclude the specific file "_cache" (note, it has NO extension) . Do all this for a whole directory tree I notice that CREATEFILTER uses "glob syntax" (http://docs.basex.org/wiki/Commands#Glob_Syntax) Questions: 1. Since this is a java program, does that mean that: http://docs.oracle.com/javase/tutorial/essential/io/fileOps.html#glob and http://docs.oracle.com/javase/7/docs/api/java/nio/file/FileSystem.html#getPa thMatcher%28java.lang.String%29 provide the exact full description of "glob syntax" for BaseX? 2. If so, can I do what I want to do with some sort of a "!" (negation) pattern? 3. Should this work with version 6.3.5 of BaseX? Thanks! David <mailto:david@leighweb.com> DavidEmailSig
