Econ Technologies has updated ChronoSync, its synchronisation and backup application, to version 3.3.3.

ChronoSync will synchronise or back up files and folders between folders on your Mac, other Macs, PCs, external drives or iPods.

This is a maintenance release of the Universal application (runs natively on Intel and PowerPC Macs) that fixes a few bugs discovered since the release of Mac OS X 10.4.8.

The release fixes a problem that led to permissions errors on locked files. It also addresses an error which could cause a file copy failure in certain situations.

A demo version is available, the application costs $30. Updates are free to registered users.
