It was inevitable. The Ziplight spotlight plugin has been rendered superfluous by a built-in Archives.mdimporter that ships with OS X 10.6 (Snow Leopard). Since OS X 10.4′s release, so many asked “why on earth didn’t Apple include the ability to search inside zip files?” The answer may shock you.
Okay, it won’t shock you. I just wanted attention. I created the Ziplight plugin to be able to search for file names inside zip files. This was mainly for my CopyWrite project backups (which are zip files). I thought it would be very useful for people to be able to have at least the titles of files in their zip archives show up in Spotlight searches. I was right.
The main limitation is that, because of the way Spotlight (1 file, 1 entry) works, you could not index the contents of files inside a zip file. Things are further complicated by the fact that expanding zip files to index their contents might eat up the last remaining disk space on users’ computers. That’s an unacceptable risk. So it appears Apple’s built-in Archives.mdimporter has this same limitation: file names only.
Ziplight is still useful for those who haven’t upgraded (or can’t because they own an older, PowerPC-based Mac). Because of this, Ziplight will remain available for download on the Bartas Technologies web site. It is, has always been, and will always be free of charge.
