I have digital photos dating back to 1999. 67 GB worth, more than 60,000 photos, all neatly organized in roughly 100+ folders by date and location. (Example: 2014-08 - Signal Peak 4x4 trail.) Now that I have made the move to Mac, I am not sure I want to forego my file system and just dump it all into iPhoto, where it organizes for you in one master file (called "managed library"). I see that iPhoto has an option for "Referenced Library," where it keeps your file/folder structure intact. For those of you that have thousands of neatly managed photos, is there any reason for me to NOT go the "referenced library" way, or is that just my old-school Windows "do it myself the hard way" habit speaking up?
