Description of the Situation:
177,000 jpg files in a folder (mostly individual frames rendered for 5 minute animation)
Needed to sort the files into sub-folders (because transition from Mavericks to Yosemite corrupted the Time Machine backups of the files, destroying file names/sequence coding and sub-folder organization). By the way, I had to purchase a file recovery application, and run it for 14 hours in order to recover the jpg files from the corrupted Time Machine backup drive. Another twist in this debacle is that Apple changed the iPhoto application to Photo with the change from Mavericks to Yosemite. Yes, all my images were in iPhoto, and NO, they did not translate smoothly to Photo. Imagine that, Apple completely dropped the ball. Has that ever happened before?
Moving a single file from the main folder to a sub-folder was taking as long as 30 seconds. Moving corrupted jpg files to trash took even longer. At 177,000 files, that is unworkable within my “Use Before” life expectancy.
Strategies tried: turn off spotlight, reduce transparency, empty cache files, run OnyX and C.o.c.k.t.a.i.l (not “rock” that the silly censor substituted), Terminal hacks, repair permissions, verify/repair disks, reinstall OSX (twice), etc
In case anyone is interested, I have a solution for this problem. Don’t use the latest, top-of-the-line Mac Mini for serious (or even casual) use. Don’t use Yosemite OSX, the Finder is defective. A 5-year old mid-line Windows machine will run rings around it, at one-third the expense.
