Hi there, I recently subscribed to Dropbox Pro. One of the reasons was I wanted to put my iTunes library there so it would sync across all my computers. My music library is around 12000 files, approximately 140gb. I use both Windows and macOS, and when doing a test using a small selection of my music files, I found that if I made sure that my Dropbox folder was at C:/Users/Dropbox and /Users/Dropbox for Windows and macOS respectively, both OS's would see the mp3 files and play properly without any messing around, and while using just one single iTunes Library. What I didn't realise was going to happen, was when I set up the library and added all my music files to it, when I open the library on a different OS than when it was previously opened (i.e. I used it on macOS and then later opened it on Windows), it goes through an 'Updating iTunes library' dialogue. On my Macbook Pro, this isn't an issue as the library is stored on a fast SSD drive and it takes a few seconds. But on my Windows machine and I am guessing on a Mac mini I use as a HTPC, which both have the library stored on standard hard drives, it takes 10 minutes to run through this process. This will only get worse as I add to my music collection. I wanted to keep one single iTunes Library so that I wouldn't have to maintain 2 sets of playlists; and my play counts would update across all devices. Does anyone know if there is a way to work around this without having 2 separate librarys? Thank you.
