CmdSync is a command line file/folder synchronizer designed for batch/scheduled operation.
CmdSync has the ability to compare file timestamps and then copy the files from each path to the other to ensure that the most up-to-date copy of the files exists in either or both paths. Additionally files that only exist on one of the paths can be specified for deletion.
Command line options:
-Source to Target
-Target to Source
-Ignore two second time diferences
