Yes, there are various user-level utilities for compressing files, like Clusters (http://clustersapp.com <http://clustersapp.com/>). The `ditto` tool also has a flag for compressing the destination file (--compress, I think). Theoretically anything on an HFS+ volume can be compressed, except for a few files in /System that need to be read early at boot before the file-compression subsystem comes online. I looked around a bit but couldn’t find any info about an API for compressing files. I’d be leery of constructing those extended attributes or resource forks myself. I suppose one could use NSTask to invoke `ditto`. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
