but it's cocoa question. But I could be probably more specific - is
there anything I need to do to support saving to network volumes
using this method?
- (BOOL)writeToFile:(NSString *)path atomically:(BOOL)flag
That'll work fine. Be sure to use the atomic mode, which is safer in
the case where another user is accessing the old file (it moves the
old file aside instead of overwriting it in place.)
Saving to a network volume is mostly the same as a local filesystem.
It's when you get to issues like file locking and permissions that
there can be differences.
I don't see how this relates to Photoshop, though. It's a Carbon app
and uses a different set of APIs for saving. It might also be using
optimizations/tricks such as incrementally updating portions of the
file.
