Is it just me being new to macs that I have this problem or is it actualy a limitation of finder itself on osx? I have noticed that if u want to copy a folder of data which has files in it that you allready have made a copy of you have to tell finder to replace all the files. For example I'll have like my documents folder then i add a large amounte of new files to it then want to back it up to a folder on a server over my lan. Instead of just being copy it to my server were it just automaticly adds the new stuff to the server I have to hit replace when i copy the documents folder over then it replaces all the files and takes quite a long time when your dealing with about 10gb of data or more even on a gigabit lan or a local drive. Now coming from windows I know it would just copy all the new files over and not take so long because its not recopying everything over again.
