I have a similar problem - same error report of "one or more busy items that cannot be changed". I am simply trying to copy my iTunes library to an external drive as a backup - as suggested
Here. So I figure there shouldn't be any reason it would not normally work.
Does anyone have an easy solution to copying large folders without the Finder getting in the way with busy, locked or permissions lacking files? Is there anything analogous to Carbon Copy Cloner for a Folder level rather than drive? Is there a terminal option? RSync? Anything else?
As Terence will tell you (see
My Other Recent Question) - I had similar problems backing up my iPhoto library and tried reseting permissions including some ACL type on a number of my individual .jpg files. This just led to iPhoto refusing to open the library entirely, and Terence had little sympathy for me given I had fiddled with permissions! He and I can't see any other way to do it mind you, and I remain unable to fully duplicate my old iPhoto library - I have now constructed a new one, only losing a few photos, and unlike the old, I can just drag and drop to backup the new. The process took me all weekend mind-you.
I agree with Bioinformatics entirely - this has been a recurrent gripe of mine. Whenever I have try to copy or move anything like a large folder there invariably evolves a series of problems with files in use, locked, incorrect permissions, and more recently a new entity to me - ACL permissions. The default response of OS X is just to dump the whole operation mid-way and give no helpful feedback on the offending file. As I have told Terence before, I have often wound up piecemeal copying folders by finding how far (seems to progress alphabetically) the process got, skipping the next file and continuing from there. This really is a joke - it takes long hours of user attention and loses the offending files forever - and rarely can I see why these files have caused a problem.
