Error: Unable to copy complete file to device

An unexpected error occurred while copying the file to the connected device.

A common cause of this problem is Android not reporting that it's out of space on the device when syncing over USB MTP mode. Please check to make sure that the files that you are syncing will fit on the device's available free space.

Another cause may be that the file can not be found. This can be triggered by iTunes deleting a file and doubleTwist Sync not updating it's internal database properly.

Otherwise, the log file might show more details about the reason for this error.

You can view the log file by using the Debug menu. The Debug menu can be accessed by holding down SHIFT as you right-click on the doubleTwist icon.

You can also send a debug package to doubleTwist Support about this issue.
