Namexif is a tool to automatically rename photos with the date they were shot. Digital cameras have their own clock and record the date to each photos with a precision of a second. Namexif uses these data to rename photo filenames. Different format are available and user can also add a keyword. Doing so will make chronological order same as alphabetical one and set a unique name to your photos. It is also possible to shift the time while renaming, allowing synchronization of different photos set about a same event, or to reflect a time zone change.
