Thanks RomanZ, your idea for the Read-only makes perfect sense and if things get crazy I'll use that. For anyone else using BitTorrent Sync but don't want to use the Read-Only idea, I just found a tip that works : #1. Make sure you can see hidden files on your computer. #2. Open .SyncIgnore with Notepad. #3. Paste this below everything that's already typed in : #Unity Ignore files/folder below *.sln *.userprefs *.csproj *.pidb *.unityproj .DS_Store /Library/FailedAssetImports.txt /Library/cache/ /Library/previews/ /Library/ScriptAssemblies /obj /Temp This makes it so I can still work with my project from place to place and not have BitTorrent accidently change anything. Thanks again RomanZ!
