Remembering IFilters
Categories
OK. Quick bug fix to my previous post. I said that when you selected "Index Properties Only", it stripped the registered IFilter from the file type. Strictly speaking, it copies the existing "persistent handler" class id, saves it in a value of "OriginalPersistentHandler" and then deletes the current registration.
This way, when you reselect "Index Properties and File Contents", it can copy the original value back, and use the proper IFilter and not have to default to the Plain Text filter.
Just the facts, ma'am.
