So, there I was moving some files from a file server to my local hard drive, and suddenly it stopped and told me that I had insufficient priviledges to complete this operation. I went and fixed the permissions, and resumed moving the files. As expected, OSX asked me if I wanted to replace the existing folder in the destination location, so I clicked YES. GRRRRRRR.... I thought it meant it was going to MERGE the two folders like it does in windows, but no.... it wiped the entire current contents of the destination folder! Does anyone know if it is possible to make this behave like it does in windows, ie when you copy one folder over another one with the same name, it merges their contents?
