Since it needs an index to iterate over, you can use the file type to just check the files you need, or even "name=*" to iterate over all files. The query would be something like name=*&&attribute="", but that only works for strings I think. Or maybe you could try name=*&&attribute!=* I added a couple of operators in my RAM file system for testing attribute existance, <>attribute for files including that attribute, and ><attribute for ones that don't have it (think of the > and < together making an X shape to cross out the possibility of existance). But since the query language is implemented by each file system (some wasted effort there - the OS should just provide indices, let library code do queries), those operators are only in AGMSRAMFileSystem. - Alex
