There are various reasons why there might be problems synchronising your files:
- The file has been locked by another application. This means that the file is currently being used in another process and could not be read by myCloud Desktop.
- The number of files and folders in your sync folder is too large. You can find more information about this here.
- You’re attempting to synchronise an unsupported file type or a file with an unsupported file name. You can find more information about this here.
