If you have modified a file without doing a 'p4 edit' and if there is a new version of the edited file on p4 (from what you have got from a previous 'p4 sync'), 'p4 sync' will overwrite your changes (if the file does not have write perm set or if you have enabled clobbering of writable files). Whereas 'p4 sync -f' will always overwrite all unopened files if a newer version is available.
