My Photos library is very large, Get Info notes that it is 69gb. I have the library stored on an external hard drive. I just purchased a new, larger external hard drive and tried to click and drag the library from one drive (in finder) to the other. However, Finder says that the file size is closer to 200gb, and it transfers up to about 73gb and gives me an error "You can't copy Photos Library because it has the same name as another item on the destination volume, and that volume doesn't distinguish between upper and lower case letters in filenames." There are no other files on the new hard drive. Any ideas what I can do?
Thanks in advance.
