USB keys are very useful for transporting information, but it can quickly become difficult to remember which files are the most up to date.
Goodsync solves this problem by making sure the latest copies of files are automatically copied between computers.
Multiple jobs can be created so it is possible to use this for simple backups, as well as keeping on top of multiple file versions. Jobs can also be set to only work in particular directions so the original files are untouched.
Note that with this free version, after 30 days you can have three synchronisation jobs set up, each with a limit of 100 files at any one point in time.
