I have a large (~90 GB) music folder synced between a mac and a PC. The BT Sync client says they are both in sync and with the correct size, but the actual size of the folder on the Mac hard drive is about 6 GB more than on the PC. I have looked through to try to spot the difference, but I don't see any obvious extra or duplicate files, subfolders, etc. But there is a lot to look through, I could have missed something. Does anyone have an idea of what it could be? I was thinking possibly the Spotlight index data, but I don't know where that lives. Thanks!
