at the moment extended properties are loaded by looping first 1000 extended properties for a file using shell32.
there should be a way to get a list of indices or a count of available extended properties for a given file.
these extended properties are based on the available columns for properties in a shell folder. some indices are skipped for some files, meaning its column is non existent. getting a count of columns would not take into account this scenario. at minimum the max icolumn index would be needed.
