Thank you Ken. That sounds really promising. I will tell you about the results. With the old and the new method. Thanks!

I have a feeling it's these: isFilePackageAtPath kLSItemInfoIsInvisible kFSNodeLockedMask kFSCatInfoCreateDate kFSCatInfoContentMod kFSCatInfoBackupDate kFSCatInfoAccessDate And parsing "ls" output won't get you these (besides, parsing "ls" is a dirty hack anyway). You probably want to try dropping down to CFURLEnumerator and asking it to prefetch the desired attributes. Or, if you're targeting pre-10.6 then FSGetCatalogInfoBulk().
