+During the update process, UNIT3D differences all files and prompts the user to choose whether to keep the current version or update to the new one; typically, it is recommended to update all files, but before beginning the update, the most recent backup should be copied to `~/tempBackup`, and after the update, the list of file conflicts is saved as `~/tempBackup/fileConflicts.txt` so that, once the process is complete, these files can be reviewed to determine which changes should be merged or discarded.
