Does handheld sync work something like this;

- collect files to sync
- for each file
    - calculate target file location
    - check if "matching" file exists (i.e. full path + size/date?)
    - if yes, ignore
    - if no, sync

or is it a bit smarter? e.g. it maintains a hash for each file (some sort of hash based on the metadata perhaps) and is thus able to spot trivial changes (e.g. the expression used to generate the path on the target device) and just move that file into the right place
