Copying Updated Files
There are two different ways to copy updated files (that is, copy newer files over the top of older ones) automatically:
The Update All and Update Existing commands offer a simple one-way form of file synchronization
The Synchronize tool offers a full, two-way synchronization system, that lets you see and control which files are going to be copied or deleted
The "Update" commands
The Update All and Update Existing commands are found in the drop-down menu attached to the Copy Files button on the default toolbar.
These two commands are variants of the standard Copy Files command, and rely on the source and destination concept. Selected files will be copied from the current source file display to the destination folder, under the following conditions:
Update All: Files will be copied if they
Don't already exist in the destination, or
Do exist in the destination, but are a different size or older than the files being copied
Update Existing: Files will be copied if they
Do exist in the destination, and
Are a different size or older than the files being copied (this rule can be modified, see below).
Files that don't match those conditions are skipped. You can modify the test conditions using the arguments for the internal Copy command:
Update All: The UPDATETOLERANCE argument can be used to control how different a timestamp can be before it is considered as "older".
Update Existing: As well as UPDATETOLERANCE, the UPDATEEXISTING argument can be used to ignore file size or date for the comparison
See the description of the internal Copy command for details on these arguments, and the Customize section for information on configuring toolbar buttons.
