File Mirror is a tiny little free utility that helps to mirror one folder to another folder. Any changes that is made to the contents of the source folder, including changes to a file, are automatically carried out in the destination folder also.
There is not much that you need to do to get it going. Once you download and install the application you have to make just three settings: set the source folder, set the destination folder and set the time interval at which File Mirror will check for changes. The time is set in milliseconds. So for a 1 second interval you would enter 1000.
Once you click Save, File Mirror will start checking the source folder for any changes and if it finds any it will sync them.
You can mirror only one folder with an instance of File Mirror. But there is a way to work around the problem. Just make a copy of the File Mirror file and rename to something else. This way you can create multiple instance of the application and thereby sync more than one folder at a time. Each instance creates its own configuration file that stores the settings for the instance.
You could use File Mirror in various situations to simplify your work. For instance you could use it to keep a backup of your favorite folder. Or you could use it to sync your files with your pen drive (usb drive). In a networked setup you could sync two folders in different Workstations using File Mirror, provided the folders are shared.
