I was wondering, is there a best practice to write an OSX programm that copies or moves a file from one place to another?

  • is there some NSSomething method I can call?
  • Do I have to work with Input/Output streams?
  • Or is the best way maybe to just rely on passing commands to the finder?

Bonus question: How do I get percentages a la ‘copy 12% complete’ with one of these methods?

Thanks for your help!

  1. NSFileManager and NSWorkspace both have methods to move, copy, and delete files. Usually you’d use NSFileManager since its easier to work with:

    if ( [[NSFileManager defaultManager] isReadableFileAtPath:source] )     [[NSFileManager defaultManager] copyItemAtURL:source toURL:destination error:nil];

    However, NSWorkspace can easily move files to the Trash, which NSFileManager can’t do.

    [[NSWorkspace sharedWorkspace] performFileOperation:NSWorkspaceRecycleOperation source:foldername destination:@'' files:filenamesArray tag:&tag];

    Check the documentation for a more complete description of the two classes. (NSFileManager, NSWorkspace)
