Window Options

The Window Options box contains miscellaneous settings:

 

DiffMerge can optionally automatically rescan the filesystem and look for files that have been modified by other applications. This rescan is performed each time a Folder Diff Window comes to the foreground and becomes the active window.

Tip

This option can be very expensive and annoying if you are comparing large folders. Disable it if restacking windows causes an unacceptable delay.
